With their first workout scheduled to begin in three days, the Spurs are close to finalizing their training camp roster.

Point guard Igor Rakocevic, centers Sean Marks and Ernest Brown and guard Larry Ayuso all have been invited and given non-guaranteed contracts.

Forward Dan Langhi and Brazilian guard Alex Ribeiro also may be added to the roster before Tuesday.

Rakocevic played 42 games for Minnesota last season while Marks appeared in 44 games the past two years with Miami. Brown, a former second-round pick of Miami, spent last season in the NBA's developmental league. Ayuso played on Puerto Rico's national team during the recent Olympic qualifying tournament in San Juan.

Of the 12 Spurs with guaranteed contracts, six are holdovers from last year's playoff roster.
