49ers RB Christian McCaffrey told reporters Monday that he's "definitely close" to 100% recovered from his knee injury. He suffered a right PCL injury in Week 13 that ended his season. McCaffrey believes he could have played if San Francisco had made the playoffs, though, and expects to be ready for OTAs. He also said that his Achilles tendonitis has "100% calmed down" and won't be an issue next season.

Niners HC Kyle Shanahan confirmed Monday that RB Christian McCaffrey will miss at least the rest of the regular season with the PCL injury in his right knee. He also revealed that RB Jordan Mason will head to IR with a high-ankle sprain.

49ers HC Kyle Shanahan said after Sunday night's loss to the Bills that RB Christian McCaffrey has a PCL injury that could be season-ending. McCaffrey will likely undergo additional testing on Monday to get a better look at the damage. We should get another update on his status over the next 24 hours. McCaffrey's absence would leave Jordan Mason as San Francisco's lead back once again. He out-carried RB Isaac Guerendo 13 to four in Buffalo. Mason, who's rostered in only 37% of Sleeper leagues, is the top target on waiver wires this week.
