The Sixers have added another player to their training camp roster, signing Hollis Thompson, according to Mark Deeks of ShamSports.com (via Twitter). The addition of Thompson will bring the team's roster count to 18 players.
Thompson, 22, went undrafted out of Georgetown a year ago. He participated in camp with the Thunder, but was cut before the start of the season, and spent the year with OKC's D-League affiliate, the Tulsa 66ers. In 48 games with the 66ers, Thompson wasn't overly productive, averaging 8.1 PPG and 3.8 RPG to go along with .447/.288/.722 shooting.
Sixers camp is expected to be fairly wide open next month. With only 11 players on fully guaranteed contracts, there should be room for Thompson and other invitees to compete for roster spots.
