The Celtics are going to have to overcome yet another setback. And for a second time, it's because of a heart issue.

Forward Chris Wilcox was said to be out indefinitely because of an undisclosed heart problem, but will now miss the remainder of the season, according to a team release. The team says it's expected he can resume basketball again next season.
A team of leading cardiac specialists who consulted with Wilcox and the Celtics indicated that surgery should completely repair Wilcox’s condition and that he can expect to resume his NBA career next season. Wilcox has long had an aortic abnormality that remained stable throughout his 10-year NBA career.

However, as a precautionary measure, the Celtics medical staff scheduled frequent aortic scans for Wilcox, and a recent scan showed a significant enlargement of his aorta. After several follow-up tests, doctors recommended surgery.
Said Danny Ainge in a statement: “While we are saddened that Chris will not be able to play again this season, the most important thing is his health, and we were fortunate to have access to an amazing team of specialists to evaluate Chris’s case. The entire Celtics family supports Chris during this difficult time in his career.”

Wilcox was having a pretty productive season off the Boston bench, becoming one of their key rotation bigs. Now without him, the Celtics are left extremely thin on the interior. There's Kevin Garnett, the always-injured Jermaine O'Neal, rookie JaJuan Johnson and Greg Stiemsma.

As for adding another piece before the deadline, it's probably unlikely to happen, but you can be sure Danny Ainge has his eye on the buy-out situation surrounding Chris Kaman. If the Hornets ended up letting him go, the Celtics will almost assuredly be a very interest party.

Wilcox, 29, was averaging 5.4 points and 4.4 rebounds in 17.2 minutes per game off of Boston's bench this season.
