The only scholarship running back Pitt practiced with in the spring was Ray Graham. The Panthers will bring in four freshman running backs in the fall.
Brown redshirted last season and is expected to be eligible to play in the fall after finishing his history degree. Brown ran for 568 yards as a freshman, but saw his playing time diminish as a sophomore and junior.
He decided to redshirt last year, with the Badgers boasting a group of backs that included Montee Ball, James White and John Clay.
Clay left school early, but Brown never jumped up the depth chart this spring.
