Michigan football beat Purdue in Week 10 on Saturday, Nov. 1, 21-16, but it wasn't pretty.

The No. 21 Wolverines (7-2, 5-1) beat Purdue 21-16 Saturday night at Michigan Stadium but didn’t look impressive in the process.

Michigan should be OK without Haynes against Purdue as running back Jordan Marshall fills in, but down the line against Ohio State and in other games it could be a big problem if he's out long term.
