SANTA CLARA, Calif.—San Francisco 49ers star running back Christian McCaffrey will not need surgery on his injured right knee but he will miss the rest of the regular season.
Coach Kyle Shanahan said Monday that McCaffrey will be out at least six weeks after injuring his posterior cruciate ligament in a loss to the Buffalo Bills on Sunday night. McCaffrey will be placed on injured reserve for the second time this season after previously missing the first eight games with Achilles tendinitis.
