Anthony, 30, has averaged 22.9 points through 21 games.
Per the NY Daily News:
According to a source, Anthony has been playing with left knee soreness for much of the season and the fear is that it may require surgery to correct. Following Tuesday’s loss at New Orleans, Anthony admitted that he’s playing with pain and hinted that he may need time off to rest.
“At this point, it’s evaluating and seeing,” Anthony said. “Some days are better than others. It’s a matter if I want to continue to play on it and the pain threshold. The flip side to that is we are losing games. I hate it, I hate to sit on the sidelines and watch my teammates. At this point, sitting down with trainers and coaches and seeing what’s best for everybody. If it’s best for me to sit out, take some time to get it right, then that’s a decision we’ll have to make. But they’ll have to pull me out.”
It is believed that if in fact surgery is needed Anthony could postpone the procedure until after the season but his most recent comments reveal a player who is concerned that his knee is not improving. Throughout his career, Anthony has shown a willingness to play hurt, including the finishing the playoffs two years ago despite suffering from a partially torn labrum in his left shoulder. […] But with the Knicks season already spiraling out of control in early December, Anthony and the Knicks may decide to take a more proactive and aggressive approach in dealing with his knee injury.
