Boston Celtics forward/center Joel Anthony will exercise his player option for the 2014-15 season and return to the C’s, a league source informed Although Anthony isn’t too thrilled with the current rebuilding phase of the organization, passing up a sizable guaranteed salary is not something he’s willing to do, the source explained. Anthony, 31, will earn $3.8 million next season and become an unrestricted free agent at the conclusion of the 2014-15 campaign. If he had elected to opt out, he would have become an unrestricted free agent this summer.
