One day after J.J. Wilcox backed out of a one-year deal, the 49ers are moving on. On Wednesday, the Niners announced that they have re-signed safety Antone Exum.

Exum played in two games with the 49ers late last season after joining the club in November. The former sixth-round pick of Vikings registered three tackles in limited action. In his three years with Minnesota, Exum appeared in 27 games (two starts) and recorded 19 tackles, two fumble recoveries, and one forced fumble on defense.
Exum will push to make the Niners’ final cut as one of the backups to Jimmie Ward and Jaquiski Tartt. One backup safety spot is already spoken for thanks to the presence of third-round pick Tarvarius Moore, but the competition is fairly open after that. If Exum can display his special teams skills this summer, the odds may be in his favor.
