EDEN PRAIRIE, Minn. -- Linebacker Chad Greenway was listed as questionable for the Minnesota Vikings' game on Sunday against the Buffalo Bills.

Offensive coordinator Norv Turner, speaking in Mike Zimmer's absence as the head coach was having a "minor procedue" on Friday, said Greenway will be a game-time decision on Sunday against Buffalo.

Greenway, however, said he'll play if it's at all possible. "If there's a way," he said, "I promise I'll be out there."

The linebacker has missed the Vikings' last three games with broken ribs, and he would wear some kind of protection if he's on the field Sunday. He was a full participant in practice for the third straight day on Friday and said he continues to feel better. He'd likely return to his starting weakside linebacker spot on Sunday with Gerald Hodges out because of a hamstring injury. If Greenway is unable to go, Audie Cole would be next in line.

Greenway broke three ribs on Sept. 21 against New Orleans, and the Vikings decided to hold him out for the following game against the Atlanta Falcons. "After the New Orleans game, we made the right call," he said. "It needed a few weeks, and it's progressing how everybody thought it would. To me, it's the most frustrating injury I've had, because what do you do? You sit around and wait for it to heal itself."

Defensive tackle Sharrif Floyd is also questionable for Sunday with elbow and ankle injuries. Defensive end Corey Wootton will miss Sunday's game with a low back injury, meaning rookie Scott Crichton will likely return to the active roster after being deactivated for the last five games.

Crichton said he has been on the first field goal unit this week, and he worked at left end this week,after playing right end all season. The Vikings have used Wootton to spell both Brian Robison and Everson Griffen, and they'll likely move Crichton into that spot this weekend.

"This is the opportunity I've been waiting for," he said.
