-- 49ers: TE Vernon Davis, K Jeff Reed.

-- Chargers: QB Philip Rivers, WR Vincent Jackson, WR Malcom Floyd, K Nate Kaeding, defense and special teams.

Quick slants: Davis has 744 yards and six touchdowns on the season, and he has nine catches for 196 yards and two scores in his last two games. ... In two games with San Francisco, Reed has scored 26 points and is perfect on seven field-goal attempts. ... Rivers has endured his only "slump" of the season, throwing for a combined 691 yards, three TDs and two interceptions in his last three games. With 3,868 yards and 26 TDs on the season, you have to play him every week. ... Jackson made it through an entire game last week, but had only two catches for 29 yards and one rush for 14 yards. Just a hunch: With Floyd banged up, this will be Jackson's breakout game. ... Floyd is a difficult call, since he missed practice Wednesday with a hamstring injury, but he's expected to play and he had four catches and two TDs last week. The Chargers' receiving corps is banged up, so they need him tonight. ... Kaeding is averaging 7.6 points per game. ... San Diego's defense is ranked first overall (265 yards per game), first against the pass (173) and fourth vs. the run (91.6).

SIT 'EM

49ers: QB Alex Smith, RB Brian Westbrook, RB Anthony Dixon, WR Michael Crabtree, WR Josh Morgan, defense and special teams.

Chargers: RB Mike Tolbert, RB Ryan Mathews, WR Patrick Crayton, TE Antonio Gates, TE Randy McMichael.

Quick slants: Smith threw for 255 yards and three TDs last week, his first game since Week 7, but I wouldn't play him against a defense that has one more interception (13) than TD passes allowed (12). ... Westbrook is a tempting play in point-per-reception leagues after he caught six passes for 87 yards and a TD last week against Seattle. In standard formats, however, I wouldn't start him because he's had only 18 carries for 54 yards in the two games in which Frank Gore has missed. ... Crabtree had one catch for 1 yard last week, and he hasn't had more than 48 yards in a game since Week 10. ... The 49ers' defense ranks 11th overall (327.4 yards per game), but is 20th against the pass (227). ... Tolbert has 10 TDs on the ground, but he split 32 carries with Mathews last week, and the rookie is San Diego's featured back when healthy (which hasn't been often). ... Mathews had 16 carries for 65 yards and a TD last week, his first appearance since Week 9, but Tolbert gets the majority of the goal-line work. ... Crayton is out with a wrist injury. ... Gates is doubtful with foot and ankle injuries. ... With Gates out last week, his replacement, McMichaels, had only two catches for 26 yards.

In a column for Friday's print and online editions, we address Randy Moss' value as a Titan, along with the emergence of Jacob Tamme as a top-10 option at tight end because of all the injuries at the position.

Until then, let's update more key injuries as we enter Week 9:

-- Cardinals running back Beanie Wells suffered an allergic reaction to a lubricant injection in his right knee (unfortunately, it always seems to be something with this former Buckeye). He plans to practice Friday, and he's scored a touchdown in two consecutive games. Arizona's opponent Sunday, the Vikings, rank 13th against the run, an uncharacteristically high number for Minnesota. If Wells is active (the Cardinals play at 1 p.m., so time won't be an issue), I'd consider him a flex play in 12-team leagues.

-- Colts running backs Joseph Addai (neck and shoulder injuries) and Mike Hart (ankle) didn't practice Thursday, and both seem to be doubtful for Sunday's game at Philadelphia. Enter Donald Brown and Javarris James. The latter is a rookie from Miami with three carries for 4 yards. The former is a 2009 first-round pick who hasn't lived up to expectations and has been outplayed by Hart, a sixth-round selection in 2008. Of the two, I'd play Brown, but only if both Addai and Hart are inactive. The Eagles rank 18th against the run.

-- Panthers running back DeAngelo Williams (foot) is expected to sit for a second consecutive week. Jonathan Stewart (14 carries for 30 yards) was a bust last week, but I would start him Sunday against the Saints, considering six teams have a bye this weekend -- making Stewart a top-20 back almost by default. The Saints are the league's No. 16 run defense, but have allowed only two rushing TDs in eight games.

-- Colts receiver Austin Collie practiced fully Thursday and is in line to start Sunday, which is a week or two earlier than we were led to believe he would return. He's a must play, especially with Anthony Gonzalez again hampered by an injury (this time, his knee).

-- Up-and-down Seahawks receiver Mike Williams missed practice Wednesday with a bruised knee, and Seattle will face the league's top pass defense Sunday in the Giants. I wouldn't play him unless you're desperate for a third receiver.

-- Packers receiver Donald Driver, who hasn't had a catch in his last two games, won't play Sunday against the visiting Cowboys because of a quadriceps injury. He is expected back in Week 11, following the Packers' bye next week. If you are looking for help, teammates James Jones and Jordy Nelson will be the Nos. 2 and 3 receivers. Jones, who had four catches for 107 yards in Week 7, is the better start in leagues that don't award a point per reception. Nelson should be the more productive of the two in PPR leagues after catching 13 passes in his last three games. The 2008 second-round pick hasn't scored a touchdown this season.

-- Chargers receiver Malcom Floyd probably will miss a third consecutive game with a hamstring injury. Sounds like a good week to start teammate Patrick Crayton against the Texans, who are giving up a league-worst 299 passing yards per game.

-- Texans receiver Andre Johnson isn't practicing because of a sore ankle, but he's expected to play Sunday. The Texans play at 1, so by now you know the drill with A.J., who always produces and always seems to have a lingering injury.

-- Vikings receiver Percy Harvin lost Moss, who significantly increased his fantasy value, as a teammate on Monday. Now Harvin might be out because of an ankle injury. With Harvin banged up and Sidney Rice not ready to return, Bernard Berrian could return to a prominent role in the passing game. Minnesota will play host to Arizona on Sunday. The Cards rank 21st against the pass.

-- Patriots receiver Deion Branch was limited in practice by a hamstring injury. He had only one catch for 21 yards last week, and I wouldn't play him Sunday against the Browns.

Stat of the week

7.2: Yards per touch for Chiefs running back Jamaal Charles this season. He has 103 carries for 666 yards, an average of 6.5 yards per attempt, and 16 receptions for 191 yards (11.9). In Kansas City's first three games, Charles had 39 touches. In the last four contests, he has 80 touches for 527 yards (428 yards rushing, 99 receiving). I think I speak for every Charles owner when I say, thank you for coming around, Todd Haley and Charlie Weis.

Peyton Hillis is the Browns' featured back, Roy Williams is alive, Darren McFadden is for real, Lance Moore is back, and Eric Wright is still chasing Anquan Boldin.

Just another week in (cue Mark Schlereth) the National Football League.

Let's take a trip around the field from a fantasy perspective after Sunday's games:

-- I know the Browns' Hillis won't keep this going, especially once Jerome Harrison is healthy, but his Week 3 performance against a Ravens defense that didn't allow a rushing touchdown in the first two games and ranked fifth against the run in 2009 was much too impressive to ignore. Hillis, who ran for 144 yards and a touchdown on 22 carries and caught seven passes for 36 yards, has to be considered a low-level No. 2 back when Harrison doesn't play. Once Harrison returns, Hillis could still be a flex play in deeper leagues, depending on the matchup. He has 14 receptions in three games.

-- At this point, we should at least be a little concerned with Andre Johnson, who had four receptions for 64 yards and reaggravated his sprained ankle. The Texans receiver has had two poor games and one huge (a 12-catch, 158-yard, one-TD performance in Week 2) contest.

-- Hey, Steven Jackson is hurt. Didn't see that coming.

-- Beanie Wells returned for the Cardinals and, as expected, Tim Hightower wasn't worth a starting spot. Wells had 14 carries for 75 yards, and Hightower had 12 touches (11 rushes for 40 yards, one catch for zero yards). It's simple: If Wells is active, Hightower (who had 218 total yards and two TDs in the first two weeks) should be a fantasy reserve.

-- Maybe it is OK to play Mike Wallace before Ben Roethlisberger returns.

-- Chargers receiver Malcom Floyd (nine receptions for 192 yards and two TDs in the last two weeks) is now a must-start. Thank Vincent Jackson (or the stubborn A.J. Smith).

-- Boldin has crushed Derrick Mason's value. The latter has seven receptions for 82 yards and one TD in three weeks. That's a decent half for Boldin against Wright.

-- Start 'em: Raiders receiver Louis Murphy (11 catches for 210 yards and a TD in his last two games), Texans receiver Kevin Walter (one TD in each game, 16 receptions on the season), Chiefs rookie tight end Tony Moeaki (12 catches, two TDs in three games) and Patriots rookie tight end Aaron Hernandez (12 receptions for 166 yards the last two weeks; 16.2 yards per catch on the season)

-- Sit 'em: Bucs running back Cadillac Williams (139 yards, 2.5 yards per carry, zero TDs in three games) and 49ers receiver Michael Crabtree (six catches, 81 yards, zero TDs on the year).

-- Drop 'em: Browns receiver Mohamed Massaquoi (three receptions for 55 yards in three games), Bills running back Fred Jackson (no longer a factor with Marshawn Lynch getting most of the carries and C.J. Spiller as the electric change-of-pace), Giants running back Brandon Jacobs (eight carries for 25 yards the last two weeks), Jaguars quarterback David Garrard (278 yards, two TDs, five interceptions in his last two games) and Chargers running back Darren Sproles (had two touches, to Mike Tolbert's 20, with Ryan Mathews sitting because of an ankle injury).

-- I wouldn't bench Kellen Winslow Jr. yet, but I'm getting close. The Bucs tight end with the messed-up knees and the eventful past has 11 receptions for 139 yards and zero scores. He hasn't had more than four catches in a game.

-- I can understand if you bench Terrell Owens, who hasn't scored as a Bengal and is averaging only 10.9 yards on his 14 receptions.

-- If you need the roster spot, it's OK to cut Carson Palmer, whose mediocre numbers (three TDs, three interceptions) don't indicate how poorly he's played.

-- A popular waiver-wire pickup this week will be the Saints' Moore, who had six receptions for 149 yards and two TDs after catching three passes for 23 yards the first two games. With Reggie Bush out, Moore will get more looks, and remember, he was effective in 2008 (79 receptions, 928 yards, 10 TDs).

-- That sound you just heard was Panthers receiver Steve Smith telling someone how he feels about the start of the Jimmy Clausen era.
