After losing Rondo for the season, it seems that rookie Jared Sullinger will also miss the rest of the season with a back injury. He's always had back problems that also proved damaging to his draft stock, but seemed to have overcome the problems and play an important on the Celtics squad. According to Adrian Wojnarowski, "Celtics rookie Jared Sullinger will miss the rest of the season with a back injury. He will need surgery." Sullinger, who slid down draft boards in 2012 despite being a star at Ohio State (primarily because he lacks game-changing explosiveness and athleticism), has drawn rave reviews in Boston in his rookie campaign. He may not play "above the rim," but his knowledge of the game and determination to do whatever it takes to help the Celtics have certainly been noticed. In roughly 20 minutes per game this season, the 6'9", 260-pounder averaged 6.0 points and 5.9 rebounds. He's posted four double-doubles this season, including a 12-point, 16-rebound effort against the Phoenix Suns on Jan. 9. He had just worked himself into Boston's starting lineup. Among power forwards who have averaged at least 20 minutes per game, he's ranked sixth in the NBA in total rebounding rate, according to Hoopdata.com (slightly behind the likes of Tim Duncan, Kevin Love and Zach Randolph).
