Brett Favre's name has frequently appeared on the NFL's weekly injury report over 20 seasons of sprains, strains and painful hits.
This might be the last time: The Minnesota Vikings declared the 41-year-old quarterback doubtful to play Sunday at Detroit because of the lingering effects of a concussion.
Favre suffered the head injury during a Dec. 20 game against the Chicago Bears and missed Tuesday night's game at Philadelphia because of it, the second time in three weeks that he sat out after his NFL-record consecutive starts streak ended.
"I'm going to just leave it as doubtful for now, without going into any detail about it," Frazier said. "If we leave him doubtful, it should cover things with him. Never rule him out."
Favre hadn't passed the tests as of Thursday morning. Vikings spokesman Bob Hagan said the team wouldn't have an update on Favre's status Saturday.
Favre didn't speak to reporters this week, but Frazier described the quarterback's attitude as positive. As teammates stretched and warmed up before practice Friday, Favre did a little dancing on the side while music by Michael Jackson and Vanilla Ice blared on the speakers.
Rice is one of several high-profile Vikings players with expiring contracts and thus uncertain futures, with the labor dispute and the possibility of a lockout looming.
"Whatever happens after Sunday, I have no idea what it's going to be," Rice said. "I'm just going to be sitting back listening to the feedback from my agent and the guys here."
Frazier has pushed a stay-focused mentality to his players since taking over the job when Brad Childress was fired in late November.
"I think it's gone as well as could be expected, considering the circumstances that I inherited and just knowing how things were," Frazier said. "It was not the most enviable position to step into. There were more things going on beyond just football that had to be dealt with in order to bring our team together. ... Just makes me so proud of our players."
Notes: Frazier said starting S Madieu Williams (concussion) will be placed on season-ending injured reserve and CB Marcus Sherels will be promoted from the practice squad for extra depth if starter Asher Allen (abdomen) can't play. Allen, LB Erin Henderson (concussion) and FB Naufahu Tahi (ankle) are listed as questionable. ... CB Cedric Griffin was voted the team's winner of the annual Ed Block Courage Award, for coming back from a torn anterior cruciate ligament in his left knee suffered in the NFC Championship game last January. He returned in late September, tore the ACL in the right knee two weeks later and landed on IR. Griffin said he'll probably start running with a brace next week.
