SANTA CLARA — The 49ers raided the Dallas Cowboys practice squad for free safety Tyree Robinson on Tuesday.
Robinson signed a two-year deal and took the roster spot of wide receiver Pierre Garçon, who went on injured reserve because of a lingering knee issue.
The 49ers (3-10) have started eight different combinations of safeties, mostly because of injuries to Adrian Colbert, Jimmie Ward and Jaquiski Tartt, the latter of whom has dealt with shoulder stingers all year. Antone Exum started at free safety and Marcell Harris made his starting debut at strong safety in Sunday’s 20-14 win over Denver.
