Warrick, 32, last played in the NBA in 2012-13, appearing for the New Orleans Hornets and Charlotte Bobcats before he was traded by Charlotte to the Orlando Magic, who then waived the former Syracuse star. He spent last season playing for Liaoning Jiebao in China after not signing with an NBA team.
The Spurs currently have just one free roster spot with 14 players under contract for next season, but Warrick said he accepted San Antonio's workout invitation since several of the team's players have non-guaranteed deals.
Warrick has played eight total years in the NBA since the Memphis Grizzlies selected him in the first round of the 2005 NBA draft, averaging 9.4 points and 4.0 rebounds for the Grizzlies, Milwaukee Bucks, Chicago Bulls, Phoenix Suns, Hornets and Bobcats.
