The Storm on Friday added offensive lineman Lawrence Martin, a former USF Bull.
"Lawrence is a versatile player that can play at multiple positions," said team VP of football operations Jeff Gooch.
Martin (6-3, 310) will take the roster spot of another former Bull, DB Terrence Mitchell who was placed on injured reserve.
This will be Martin's first stint in Arena Football. He played at two small colleges before finishing up his final two seasons at USF.
The Storm take on Philadelphia in a critical contest Saturday afternoon at 5 p.m. Jack Harris and Darek Sharp will call play-by-play on 1250 WHNZ.
