The Browns waived Ekpre-Olomu with a non-football injury designation on Saturday. The 5’9″ corner was selected by Cleveland in the 7th round last year, but was one of the top ranked CB prospects in the 2015 draft before suffering a torn ACL and dislocating his knee at the end of his senior season.

The Steelers had the lowest priority of the 4 teams who made waiver claims on the cornerback.
