The Oklahoma City Thunder have signed free agent guard Antonio Anderson to a 10-day contract and waived forward Matt Harpring.

Thunder General Manager Sam Presti announced the moves Monday. Anderson has been with the NBA Development League's Rio Valley Grande Vipers where he averaged 15.5 points, 4 rebounds, 5.9 assists and 1.3 steals in 32 games.

Anderson is a 6-foot-6 guard who was undrafted out of Memphis in 2009. He went to training camp with the Charlotte Bobcats and appeared in five games before being waived Oct. 22.
