According to Matt Maiocco, the 49ers signed DB Antone Exum to a one-year deal and placed OL Garry Gilliam on the injured reserve.
Exum, 26, is a former sixth-round pick by the Vikings in the 2014 NFL Draft. He was entering the final year of a four-year, $2,335,788 rookie contract and was set to make a base salary of $690,000 for the 2017 season when the team waived him.
Exum landed on Minnesota’s injured reserve in 2015 with injuries to his ribs and hips, while he missed all of last year with a leg injury.
