Mark Bartelstein, Parsons' agent, said Friday night the former Florida star will leave Sunday and immediately join the team, which has already started its training camp.
The 6-foot-10 Parsons was the 38th overall pick by Houston. He was the Southeastern Conference player of the year for the 2010-11 season after averaging 11.4 points and 7.8 rebounds per game.
The NBA lockout began July 1, and slow progress in negotiations is jeopardizing the scheduled start of training camps in early October.
