The 49ers signed rookie safety Tyree Robinson off the Dallas Cowboys’ practice squad on Tuesday in order to fill the roster spot that opened with wide receiver Pierre Garçon going on injured reserve.
Garçon underwent season-ending surgery on his knee Tuesday after missing the past four games with the condition. Garçon appeared in 16 games for the 49ers over the past two seasons. He caught 64 passes for 786 yards and one touchdown.
Robinson (6-foot-2, 202 pounds) originally signed with the Cowboys as an undrafted rookie from Oregon. He was active for the Cowboys’ first two games of the season before he was waived and signed to the team’s practice squad.
