Jackson, a 5-10, 195-pound defensive back, has never played in the Arena Football League.
He played 41 games of Jacksonville University with 11 interceptions and was an all-state football player at Palmetto.
Sunday's game kicks off at 6 p.m. from the PPL Center in Allentown. Darek Sharp will have the play-by-play call on sister station 1250 WHNZ.
