Robert Griffin III practiced for the third straight day on his sprained right knee Friday, albeit again on a limited basis, and is officially listed as questionable for Sunday's game against the Cleveland Browns.
"He keeps on improving every day," coach Mike Shanahan said. "He's much better today."
Shanahan again said he will wait until Sunday to reveal whether Griffin or fellow rookie Kirk Cousins will start. He said the quarterbacks might be informed of the decision Saturday night.
Griffin, the league's top-rated passer, looked fine during Friday's session as he stretched with his teammates and made a few throws during the 15 minutes reporters were allowed to watch. It would have been difficult to tell he was injured if it weren't already known.
Griffin sprained his lateral collateral ligament when he was hit by defensive tackle Haloti Ngata late in regulation in last week's 31-28 overtime victory over the Baltimore Ravens.
Bears: Quarterback Jay Cutler appears ready to play Sunday against Green Bay. Cutler went through a full practice despite knee and neck problems and was officially listed as probable. The Bears ruled out receiver Earl Bennett (concussion), cornerback Tim Jennings (shoulder) and linebacker Brian Urlacher (hamstring).
Packers: The team expects to have linebacker Clay Matthews back in the lineup Sunday against Chicago. The team's top pass rusher has missed the last four games
Giants: Coach Tom Coughlin confirmed that leading rusher Ahmad Bradshaw will not play Sunday against Atlanta because of lingering knee and foot problems.
With the team already missing second-leading rusher Andre Brown (out for the season with a broken fibula), the Giants now will turn to rookie David Wilson, who had a spectacular game Sunday against New Orleans, as well as recent free-agent signees Ryan Torain and Kregg Lumpkin.
Seahawks: Seattle will be without starting cornerback Walter Thurmond (hamstring) against the Buffalo Bills in Toronto on Sunday. The Seahawks will be forced to start their third cornerback in three weeks. Thurmond started last week in place of Brandon Browner, who is serving a league suspension for use of performance-enhancing drugs. Either Byron Maxwell or rookie Jeremy Lane will start Sunday.
Jets: Tim Tebow might not be done in the wildcat after all. Coach Rex Ryan reversed his decision Friday, saying the backup quarterback might participate in the wildcat-style offense and on special teams as the personal punt protector at Tennessee on Monday night. On Thursday, Ryan said Tebow would be the backup to Mark Sanchez but only in the conventional offense as he continues to recover from two broken ribs.
Cowboys: Nose tackle Jay Ratliff underwent what could be season-ending surgery to repair a sports hernia. Ratliff already has missed seven games this season, including the past three with a groin injury. He was no closer to getting on the field Sunday against Pittsburgh and opted to fly to Philadelphia for the surgery.
Dolphins: Receiver Davone Bess (back) and linebacker Koa Misi (ankle) have been ruled out of Sunday's game against Jacksonville.
Bounty scandal: Jonathan Vilma urged a federal judge to reject NFL Commissioner Roger Goodell's motion to dismiss the defamation lawsuit filed against him by the Saints linebacker.
