Gophers wide receiver Derrick Engel suffered a knee injury this week that could sideline him for Saturday's showdown against Wisconsin.

Coach Jerry Kill said the team won't know the severity of Engel's injury until mid-week.

Engel, a senior from Chaska, leads the team with 25 receptions for 405 yards and five touchdowns. Engel sprained his ankle at Indiana on Nov. 2 but returned to make three catches for 40 yards in the Nov. 9 win over Penn State.

The Gophers were hoping the bye week would give everyone time to heal before the Wisconsin game on Saturday at TCF Bank Stadium.

The Gophers don't have another wide receiver with more than eight receptions or a touchdown catch this season. That list includes true freshman Drew Wolitarsky (eight catches, 109 yards), junior Isaac Fruechte (eight catches, 97 yards), true freshman Donovahn Jones (six catches, 79 yards), sophomore KJ Maye (six catches, 70 yards) and junior Logan Hutton (three catches, 31 yards).

Redshirt freshman tight end Maxx Williams is second on the team with 17 catches for 299 yards and four touchdowns, followed by running back David Cobb, who has 14 catches for 148 yards.

The Gophers lost junior cornerback Briean Boddy-Calhoun to a season-ending knee injury in the second game of the season, and starting center Jon Christenson broke his leg in the Indiana game. The team has weathered other injuries, too, but those were the two that shelved starting players for the season.
