NFL Update: Christian McCaffrey's Questionable Status for 49ers vs. Jets

SANTA CLARA -- San Francisco All-Pro running back Christian McCaffrey is listed as questionable for the season opener against the New York Jets with a sore calf and Achilles. McCaffrey got hurt early in training camp and missed four weeks of practice before returning to the field this week. He was limited all week in practice and is officially questionable for Monday night's game despite stating on Friday that he had no doubt he would play.

The 49ers also will have All-Pro left tackle Trent Williams and star receiver Brandon Aiyuk available for the opener after they missed all of training camp practices during contract disputes. Coach Kyle Shanahan mentioned on Saturday that Aiyuk could be eased back in and not get his usual full load, making it more complex with Williams as Shanahan is hopeful he can play the entire game.
