The Celtics have signed free agent guard Jamar Smith, according to Steve Bulpett of the Boston Herald. Bulpett says the move was made earlier this month, and though the team has yet to confirm the signing, Greg Payne of ESPNBoston.com says Smith has earned an official invitation to training camp in the fall. So, it's likely Smith has a non-guaranteed deal, perhaps with a team option for a second season, as RealGM.com suggests.
The 6'3" Smith, 25, went undrafted in 2010 out of Southern Indiana and played last season for BK Prostejov in the Czech Republic. The Celtics had him in camp in 2010, and he's a part of the Celtics summer league team this year. He appeared in 48 games for the Maine Red Claws, Boston's D-League affiliate, in 2010/11, racking up 13.7 points and 5.0 assists per game to go with 43.2% three-point shooting.
Bulpett adds that the team is also pursuing Dionte Christmas, a 6'5" guard out of Temple who went to camp with the Sixers in 2009.
