All-Pro running back Christian McCaffrey has been ruled out of this weekend’s game for the 49ers because of his lingering calf and Achilles’ injuries and could be headed to injured reserve.

McCaffrey was held out of practice on Friday, a day after experiencing pain in practice. He was then ruled out of the game Sunday against the Vikings after expressing hope earlier in the week that he could play.

Coach Kyle Shanahan said the team will discuss whether to shut McCaffrey down for at least four more weeks by placing him on injured reserve after saying earlier in the week that wasn’t under consideration.

“It’s something we’re considering now,” Shanahan said Friday. “Yesterday was his worst day.”
