The Minnesota Vikings released their first Week 10 injury report on Wednesday, as the Vikings prepare to host the Detroit Lions on Sunday in a pivotal NFC North game.

Vikings wide receiver Percy Harvin did not participate in practice today, but head coach Leslie Frazier is optimistic that Harvin will be able to participate in Friday's practice. Harvin sprained his left ankle during Minnesota's Week 9 loss to the Seattle Seahawks and was seen on crutches as recently as Monday.

Defensive tackle Letroy Guion also missed practice on Wednesday. Guion is battling a turf toe injury, but, like Harvin, Frazier is optimistic that Guion will be able to play on Sunday.

Fullback Jerome Felton (shoulder), offensive tackle Matt Kalil (knee) and cornerback Antoine Winfield (knee) were all listed as limited in Wednesday's practice.

Minnesota has lost three of its last four games and will certainly hope to be close to full strength on Sunday, as the Vikings look to reverse their fortunes in Week 10 against the Lions.
