Bradenton, Fla. -- Michigan's apparel contract with Adidas doesn't expire until August but several Michigan players are wearing Nike cleats during spring practice.

Michigan will be moving to Nike once the Adidas contract expires.

The Wolverines opened practice Monday at IMG Academy on Monday.

A UM official said Nike shoes have been purchased so that players can test them "periodically through the spring."

Also notable from the first day of practice, wide receiver Da'Mario Jones and offensive lineman Blake Bars are not on the roster.

Jones, from Westland John Glenn, appeared in 23 games during his three years at Michigan as a receiver and on special teams.

Bars, from Nashville, would have been a fifth-year senior in 2016. He appeared in eight games during his Michigan career.

Quarterback John O'Korn is now wearing No. 8. He sat out last season due to NCAA transfer rules but had been issued No. 5.
