Iwuoma is a 5-foot-8, 182-pound second-year player out of the University of California. He signed with the Detroit Lions last year as an undrafted free agent and played in 14 games, starting once. He made 10 tackles (four solo), defensed three passes and made 11 special teams tackles. He was released by the Lions in the 2002 preseason.
The Steelers began the season with only four cornerbacks and became even more thin at the position when reserve Hank Poteat injured his toe in the Monday night opener against the New England Patriots.
In another change, the Steelers released running back Antwon McCray of Carnegie from their practice squad and signed wide receiver Francis St. Paul. St. Paul (5-10,185) was originally drafted in the sixth round of the 2001 NFL Draft by the St. Louis Rams and spent the end of the 2001 season on the Rams practice squad.
