SEATTLE -- Free safety Eric Reid sustained a concussion Sunday night that forced him out of the 49ers’ game against the Seattle Seahawks. Reid was ruled out for the game.
He must now go through the NFL’s protocol on concussions before he will be allowed to return to practice and game action.
Reid, who became the first 49ers rookie in club history to record interceptions in his first two games, sustained the injury when he made a big hit on Seattle wide receiver Sidney Rice at the end of a 13-yard completion late in the second quarter.
Reid remained on the field for a couple minutes as the team’s medical staff tended to him. He walked off the field under his own power. Team physician Dr. Daniel Garza, a leading expert on concussions at Stanford Hospital, walked Reid back to the locker room.
Veteran Craig Dahl replaced Reid in the 49ers lineup.
Reid, who won the job to replace Dashon Goldon as the team’s starting free safety, got off to a strong start with an interception against Green Bay Packers quarterback Aaron Rodgers in the season opener.
