EAST LANSING, Mich. – Michigan State's record-setting offense was at it again in a 56-14 rout of Wyoming on Saturday in its final tuneup before the Big Ten season.

Jeremy Langford rushed for 137 of the No. 9 Spartans' 533 total yards and his 3-1 team completed its most explosive prolific four games in school history with a 50.3-point average.

Connor Cook was 6-for-8 through the air for 109 yards and two touchdowns, helping Michigan State score more than 50 points in back-to-back games for the first time since 1978.

The Spartans have scored 174 points in three home games heading into a visit from unbeaten No. 21 Nebraska next Saturday night.

Tony Lippett had four catches for 76 yards and a touchdown, and Keith Mumphery scored on a run and a reception vs. the Cowboys (3-2).
