Broncos’ C.J. Anderson has knee surgery, out indefinitely

ENGLEWOOD, Colo. -- After a morning of back-and-forth about whether he was or was not done for the season, Broncos running back C.J. Anderson underwent meniscus surgery on his right knee Thursday afternoon and is out indefinitely.

Ian Rapoport of the NFL Network tweeted at 9:11 a.m. that Anderson "has told people close to him that he's done for the year, I am told."

Almost immediately, Anderson tweeted, saying the report was false.

He later wrote, "The false report that people have is crazy we would know later today what's going on so please don't believe these false allegations."

Anderson then deleted the tweets.

But less than three hours later, Adam Schefter reported the meniscus damage and that Anderson was out indefinitely.

Anderson injured his knee in Monday's 27-9 win over the Houston Texans. He finished with 107 rushing yards.

He missed practice Wednesday and underwent an MRI on Wednesday night that showed he did not tear his ACL.

After seeking a second opinion and having more testing Thursday, the meniscus tear was revealed.

Anderson is likely headed to the injured reserve list. The question is if it's the IR with designation to return later in the season or if it will be the season-ending IR.
