Brock Lesnar’s WrestleMania opponent is likely to come in the form of a giant: Omos.

The challenge was laid down yesterday on Raw when MVP called Brock a coward for the way he got out of his match against Bobby Lashley on Saturday night in Montreal.

MVP said that Omos was challenging Lesnar to a match at WrestleMania and invited the former WWE and UFC champion to come to Raw in Grand Rapids next week to accept his challenge.

Lesnar main evented last year’s WrestleMania, losing the winner-take-all match against Roman Reigns. Omos battled Bobby Lashley on the same night, also losing his match.
