With the first practice of training camp looming next week, the Spurs’ training camp roster is beginning to take shape.
The team on Thursday formally announced four more additions, all of them forwards, including two with NBA experience:
* Derrick Brown, 6-foot-8, spent most of his three NBA seasons with the Charlotte Bobcats. The 25-year-old started 17 of 65 games with Charlotte last season, averaging 8.1 points and 3.6 rebounds.
* Josh Powell, earned championship rings as a reserve with the Los Angeles Lakers in 2009 and 2010 and last played in the NBA in 2010-11 with Atlanta. The 29-year-old, who stands 6-foot-9, spent last season in China, Switzerland and Puerto Rico.
* Tyler Wilkerson, also 6-foot-8, is a veteran of two Spurs Summer League squads. The 24-year-old spent the past two seasons playing professionally in Israel.
* Wesley Witherspoon , 6-foot-9, is an undrafted rookie out of Memphis, where he appeared in 121 games in four seasons, averaging 8.2 points and 3.7 rebounds. He was Conference USA’s Sixth Man of the Year in 2008-09.
With the signings, the Spurs’ training camp roster stands at 18, two below the maximum. The roster must be trimmed to 15 before the start of the season.
The Spurs open camp Tuesday.
