49ers signed G Garrett Chisolm and OT Kenny Wiggins to reserve/future contracts.
An undrafted rookie out of South Carolina, Chisolm bounced around between three teams’ practice squads this season. Also an undrafted rookie, Wiggins was cut loose by the 49ers in September. Interestingly, both were most recently members of the Ravens’ practice squad. Perhaps 49ers coach Jim Harbaugh is getting recommendations from his brother.
