Ole Miss recently released a Week 1 depth chart that has junior Scottie Phillips as the starter at running back, but he’ll be without his top backup against Texas Tech.

According to news that broke on Tuesday, fellow junior RB Eric Swinney will miss the first three weeks of the season.

The reason? Apparently Swinney is dealing with a bout of mononucleosis:

As a sophomore in 2017, Swinney ran for 195 yards and three touchdowns while backing up Jordan Wilkins.

Phillips won the job out of fall camp, but Swinney was still going to be counted on to provide depth, so his presence will certainly be missed as he recovers from illness.
