Golden State Warriors forward David Lee underwent successful surgery Thursday morning to address a torn right hip flexor, the team announced in a press release. Following the procedure, which was performed by Dr. William Meyers at the Vincera Institute in Philadelphia, Lee is expected to begin rehabilitation in the next 10-14 days. Lee, 30, suffered the injury in Game 1 of the Warriors’ First Round playoff series against the Denver Nuggets on April 20, 2013. After missing the next four games, Lee returned to action to play one minute, 27 seconds in Game 6, the final game of the First Round series, as Golden State defeated Denver 4-2. In the Conference Semifinals against San Antonio, Lee did not play in either of the first two games, but appeared in each of the final four contests of the series, finishing the 2013 Playoffs with averages of 5.0 points and 4.7 rebounds in 10.9 minutes over six games.
