EAST LANSING - Michigan State's offense is struggling, and its top receiver is now out.

Senior wide receiver Felton Davis suffered a left leg injury in the second quarter of Saturday's game against Michigan and FOX reported it is a torn Achilles tendon. That would be a season-ending injury.

There was no contact on the play and Davis went down just as he started his break from the line of scrimmage. Trainers looked at his left leg before he was taken off the field on a cart.

Michigan had a 7-0 lead against Michigan State at halftime and the Spartans managed just 49 yards of total offense in the first half. Davis was targeted four times in the first half but didn't have a reception.

Davis leads the Spartans in all receiving categories with 31 catches for 474 yards and four touchdowns. He had eight catches for 100 yards and two touchdowns in last week's win at Penn State - including the game-winning score with 19 seconds left in the game.

The injury to Davis is the latest blow to Michigan State's wide receivers. Starter Cody White is out indefinitely after suffering a broken hand in a Sept. 29 win against Central Michigan. Starter Darrell Stewart Jr. missed two of three games with an apparent ankle injury but returned to the field against Michigan. Jalen Nailor missed each of the last three games with an undisclosed injury but dressed against Michigan.
