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.

Click here early Friday morning to find the column.

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.
