SANTA CLARA — An already depleted 49ers defense has suffered another loss as lineman Tank Carradine has been diagnosed with a high ankle sprain and could be placed on injured reserve early next week, coach Kyle Shanahan said Friday.
Shanahan said the team will decide Monday whether to place Carradine, one of several 49ers players to be injured Thursday, on IR, in which case the 28-year old would have to miss a minimum of eight games.
“We haven’t got his MRI back, but we’re going to have to get that and really decide whether (to) IR or not,” Shanahan said.
