Vander Blue was sent to the Celtics' D-League affiliate Maine Red Claws on Friday, where he scored 13 points in a 111-100 win over the Delaware Sevens.
That wasn't enough to keep him around the C's for another 10 days though.
The Celtics will not re-new Blue's 10-day contract, according to RealGM's Shams Charania.
Charania did report that there was a chance Blue could re-sign with the team after the All-Star Break. For now, he will report back to the D-League team he was on prior to signing with the C's, the Deleware Sevens.
Blue made three appearances for the Celtics, averaging 1.7 points and 1.0 rebounds in 4.9 minutes per game.
