The Minnesota Vikings officially declared Percy Harvin doubtful for Sunday's matchup against NFC North rival Detroit, though coach Leslie Frazier didn't rule his star wide receiver out completely on Friday.
Harvin sprained his left ankle in three places during the third quarter of last week's 30-20 loss at Seattle. Though he did not come out of the contest, the playmaking wideout was spotted on crutches on Monday and did not practice the entire week.
An MRI taken Monday confirmed a significant sprain, though Harvin did not sustain any fractures.
"He'd have to make quite a bit of a recovery tomorrow for us to say, 'Okay, we'll wait until Sunday to see what you can do'," said Frazier on Friday. "But it's possible, we've seen it happen before. We're going to continue to treat him and see how he feels tomorrow."
Harvin does have a history of playing through injuries. The 24-year-old has battled a variety of ailments all throughout his four-year career, but hasn't missed a game since Week 14 of the 2010 season.
The versatile Harvin is in the midst of a terrific 2012 campaign. He entered this week atop the NFL with 62 receptions totaling 677 yards and also leads the league with a 35.9 yard average on kickoff returns.
Minnesota does have a bye in Week 11 following Sunday's showdown with the Lions.
Defensive tackle Letroy Guion, also listed as doubtful due to a turf toe injury, is the only other Vikings player in danger of missing this weekend's tilt.
