The Detroit Lions have signed two safeties in free agency, but they might not be done fortifying the position yet.
The Lions have a pre-draft visit set up with USC safety Su'a Cravens next month.
Cravens joins fellow potential first-round picks Shaq Lawson of Clemson and Jarran Reed of Alabama as prospects scheduled to make top-30 visits to the Lions.
Cravens played a hybrid outside linebacker spot for USC, but the Lions are among the teams that consider him a safety in the NFL.
He led the Trojans with 86 tackles last season, including 15 for loss.
