Varnado, a 6-foot-9 forward, averaged 14 points, 10 rebounds and 3.9 blocks per game in 10 appearances for the Sioux Falls Skyforce this season. The 24-year-old was drafted in the second round (41st overall) of the 2010 draft by the Miami Heat. He spent time in Israel and Italy before landing in the D-League this winter.

The Celtics had an open roster spot after Darko Milicic left the team last month. Boston's need for a big man was heightened when Doc Rivers disclosed today that center/forward Chris Wilcox will miss about a month due to a right thumb issue.

Varnado is an athletic big man who can rebound and block shots. The Celtics, who struck gold when they signed Greg Stiemsma last season after his time in Sioux Falls, are hoping to find another serviceable young big via the Skyforce.

Rivers said Sunday that he wasn't sure the team would ink a big man before the team's upcoming four-game road trip, but the Celtics appear to have moved quick to add depth. The addition will put Boston at the 15-man roster limit, but the Celtics could still be players at the trade deadline if they desire to seek further frontcourt upgrades.

The Celtics also have rookie center Fab Melo with Maine of the D-League, but Rivers hinted Sunday that Melo simply isn't ready for the NBA level at the moment.
