Celtics sign Ryan Hollins, waive Chris Wilcox

The Boston Celtics signed center Ryan Hollins on Friday.

The 7-foot UCLA product played in 24 games -- starting seven of them -- for the Cleveland Cavaliers this season, averaging 3.7 points and 2.3 rebounds.

To make room for Hollins, the Celtics waived forward/center Chris Wilcox, who will miss the rest of the season because of a heart ailment.
