The Boston Celtics have released Shavlik Randolph before his contract was set to become guaranteed the power forward told ESPN's Jeff Goodman.

Randolph's $1.1 million salary would have been guaranteed if the Celtics did not waive him by the end of the day Thursday.

The Celtics' roster now stands at the regular-season limit of 15 players all of whom have guaranteed contracts. Those players account for roughly $72.5 million in salary slightly over the luxury-tax threshold of about $71.75 million.

Second-round draft pick Colton Iverson remains unsigned but appears set to sign in Turkey if Boston can't find space for him.
