ASHBURN, Va. - Three days after spraining his knee, Redskins quarterback Robert Griffin III was just a little gimpy on the practice field and very cagey behind the microphone
He likes his chances of playing Sunday, but he and coach Mike Shanahan want to keep the Browns guessing as long as possible.
Wearing his No. 10 jersey and a black knee brace underneath his sweatpants on a chilly day, Griffin high-stepped and moved laterally with barely a hitch as he stretched, then favored his right leg during throwing drills as the Redskins began on-field preparations for this week's game.
"Sunday night, I thought there was probably no chance that I could play the next week," Griffin said. "And then Monday morning, I felt better about it. Yesterday, I felt better about it. And today I feel really good about it."
Griffin has a mild sprain of the lateral collateral ligament in his right knee, a favorable diagnosis considering the scary hit to his leg from defensive tackle Haloti Ngata at the end of a scramble late in regulation in Washington's 31-28 overtime victory over the Baltimore Ravens.
Cards' Kolb placed on IR
TEMPE - The Cardinals have given up hope that Kevin Kolb will return this season, placing the only quarterback who had success with the team this season on injured reserve and naming rookie Ryan Lindley as starter for Sunday's game against Detroit.
Kolb led the team to a 4-0 start this season but went down with a rib injury in Week 6 and has not played since. The team placed him on injured reserve Wednesday, two days after claiming quarterback Brian Hoyer on waivers from Pittsburgh.
"I just think in talking with the doctors and where he is physically, just being able to take a hit was the biggest concern," coach Ken Whisenhunt said, "and what kind of effect that would have on him."
The Cardinals have lost nine straight and are coming off the most one-sided loss in franchise history, 58-0 at Seattle.
• Giants coach Tom Coughlin says he has not ruled out running back Ahmad Bradshaw from Sunday's matchup in Atlanta, despite a knee injury.
Bradshaw, injured vs. New Orleans on Sunday, missed practice on Wednesday, and Coughlin kept open the possibility that rookie backup David Wilson could start against the Falcons (11-2).
• Seahawks receiver Sidney Rice has a bruised foot, is in a walking boot and could miss Sunday's game against Buffalo in Toronto.
Seattle coach Pete Carroll said Wednesday that the foot problem came out of nowhere. Rice doesn't remember aggravating the foot in Sunday's blowout win over Arizona, but he woke up Monday morning in pain.
