Pulling in a couple of fantasy thoughts from the Twitterverse.

As expected, Steelers safety Troy Polamalu will sit out Sunday’s game against the Jets with a strained right Achilles’ tendon and a sore calf. He didn’t practice all week and was listed as doubtful on Friday’s injury report.

The Cowboys have ruled out starting FS Gerald Sensabaugh and rookie LB Sean Lee out of Sunday’s game against the Redskins due to concussions.

The Broncos made ailing Kyle Orton their No. 3 QB for Sunday’s game against the Raiders, confirming that ballyhooed rookie Tim Tebow will make his first NFL start.

It’s been an all-around bad day for the Eagles at New Meadowlands Stadium, and to make matters worse FS Nate Allen has left the game with a serious knee injury.

If Michael Vick got you into the playoffs, he is about to usher you out of the playoffs if he does not turn things around quickly.

It’s an all-too-common sight this season to see Colts WR Austin Collie laid out on the field after a crushing hit. That scene played out again on Sunday against the Jaguars.

Redskins safety Reed Doughty is questionable to return to Sunday’s game against the Cowboys after suffering a head injury during the first half.

Any of you thinking of benching Vikings RB Adrian Peterson this week should take a gander at what Ravens RB Ray Rice is doing right now.

Already playing with a gimpy knee, Bengals WR Terrell Owens left Sunday’s game against the Browns during the first quarter and is questionable to return.

Titans QB Kerry Collins can still bring it. The old man outscored Colts QB Peyton Manning two weeks ago, and now he’s lighting up the Texans, as the Titans lead 21-0.

Playing their biggest game of the season in Week 15 against the Colts, the Jaguars can ill-afford to lose any playmakers. So it was a huge blow when WR Mike Sims-Walker left the game during the first quarter with an apparent right ankle injury.

Drew Stanton will start at QB for the Lions on Sunday against the Buccaneers.

The Titans pulled two lineup surprises for Sunday’s game against the Texans, deactivating TE Bo Scaife and DB Vincent Fuller. Neither player was listed on Friday’s injury report.

Saints rookie RB Chris Ivory couldn’t shake a hamstring injury, so he won’t play Sunday against the Ravens.
