Who's in and who's out for Sunday's late games? We're keeping an eye on the key injuries heading into 4:25 p.m. ET time slot ...
• Pierre Garcon, WR, Redskins: Washington's wide receiver had hoped to play after leaving his team's Week 1 win with a foot injury -- Garcon scored on a long catch-and-run pass from Robert Griffin III, then exited the game. However, Garcon was unable to go on Sunday. Aldrick Robinson will start in his place.
• Antonio Gates, TE, Chargers: A big, unexpected loss for San Diego, as the Chargers host Tennessee. Gates had been listed as questionable with a rib injury, but all indications through the week pointed toward Gates suiting up. Randy McMichael becomes San Diego's No. 1 TE option with Gates out.
• Ryan Mathews, RB, Chargers: Not a huge surprise here, though Mathews hoped he would be ready to go Sunday, just a few weeks after breaking his collarbone in San Diego's preseason opener. Ronnie Brown will open in the backfield again for the Chargers.
• Russell Okung, LT, Seahawks:Okung left Week 1 with a knee injury -- one that, at the time, appeared to be rather serious. However, Okung reportedly was diagnosed with a bone bruise and he tried to go through pregame warmups on Sunday. However, he was still hobbled and wound up on Seattle's inactive list.
• Troy Polamalu, S, Steelers: The Steelers will be without both Polamalu (calf) and James Harrison (knee) -- Harrison for the second straight week. Polamalu played in Pittsburgh's Week 1 loss to Denver but his absence should give Mark Sanchez and the Jets a boost.
• Kenny Britt, WR, Titans: Britt will make his 2011 debut after a Week 1 suspension. Britt was questionable to play against the Chargers because of a knee injury, but he's going to suit up and give it a go.
• Jake Locker, QB, Titans: More good news for the Titans. Locker left Tennessee's Week 1 game with a left shoulder injury, which he sustained trying to make a tackle. Matt Hasselbeck prepared this week to take over the Titans' offense again, but Locker will start at San Diego.
• Sidney Rice, WR, Seahawks:
It would have taken a late setback to get Rice (knee) out of the lineup Sunday -- he was listed as probable to play. Still, his return should help boost the Seattle offense and, as a result, put a little less pressure on rookie QB Russell Wilson
