The Houston Rockets signed veteran shooting guard Marcus Thornton to a one-year contract on Sunday, according to a source.
Thornton, a six-year veteran who has played with five NBA teams, averaged 7.9 points and shot 40.6 percent from the field and 37.8 percent from 3-point range last season with the Celtics and Suns.
Thornton has averaged 12.7 points while shooting 42.9 percent from the field and 36.2 percent from 3-point range.
Thornton was a second-round pick by the Miami Heat in 2009. He has played in 389 NBA games, mainly as a reserve.
The Rockets are still in need of another playmaker in the backcourt and have held discussions with veteran guard Jason Terry but have yet to finalize a deal. Restricted free-agent guard K.J. McDaniels has also been in talks with the team, and while he hasn't received an offer sheet from another team, there are indications he will return to the Rockets.
The team attempted to bring in guard Sergio Llull from Real Madrid, but he has elected to remain overseas for this season.
