The two players, both 24 years old, weren't major factors on the Celtics, only earning garbage-time minutes: Joseph was the team's second-round draft pick this year out of Syracuse, and had played in six games, scoring seven points. Varnado, the NCAA's all-time leading shot-blocker, has bounced around Europe and the D-League since graduating from Mississippi State in 2010, and had played in five games, scoring six points, since getting signed on Dec. 24.
Joseph had spent large chunks of time in the D-League with the Maine Red Claws, while Varnado had also been in the D-League before signing with Boston.
The Celtics now have two free roster spots, which could be valuable if the team tries to make a trade. Joseph and Varnado were both playing on non-guaranteed contracts, both of which would have become officially guaranteed for the rest of the season on Monday, meaning the team saves several hundred thousand dollars by making the move.
