Safety Eric Reid will miss at least one game with a left knee sprain, 49ers coach Kyle Shanahan said during a conference call on Monday.
Shanahan said Reid will definitely miss the 49ers’ game Thursday night against the Los Angeles Rams at Levi’s Stadium. The injury is likely to keep Reid out of action for more than just one game, Shanahan said. The injury is to the posterior cruciate ligament in Reid's left knee and will not require surgery, according to Shanahan.
Reid was forced to leave Sunday’s game against the Seattle Seahawks on three separate occasions. The first time he left the game in the second quarter with a non-contact injury. After the game, Reid said he left the game all three times feeling the same condition in his knee.
"They (the 49ers medical staff) didn't feel that there was anything torn, so he felt it was all right," Shanahan said. "I haven't gotten to talk to him personally, yet, so I'm not exactly sure. But when he checked out, it seemed all right. The X-ray they had looked good, and he said he could go so he kept trying to go and then he had his final straw and said he couldn't go anymore."
The 49ers are not sure about the status of safety Jaquiski Tartt for Thursday's game. Shanahan said Tartt is questionable with a neck injury.
“I know he was hurting today," Shanahan said. "We’ll see how he is when he comes in tomorrow."
Tartt and Reid have started both games. Jimmie Ward returned to action on Sunday after missing all of training camp with a hamstring injury. Rookies Lorenzo Jerome and Adrian Colbert are the only other safeties on the 49ers' roster.
