The Dallas Mavericks have made a move at small forward, agreeing with restricted free agent Chandler Parsons on a three-year offer sheet worth more than $45 million.
Houston will now have to decide whether to match the offer.
Two people with knowledge of the situation said Wednesday night that Parsons agreed to the offer sheet with the Mavericks, while a third person confirmed the terms. The people commented to The Associated Press on condition of anonymity because the offer sheet can't be officially signed until Thursday, when the NBA's moratorium on signing free agents ends.
The Rockets would then have three days to match the offer, though it wasn't immediately clear if they would do so for the 25-year-old forward who has played for them the past three seasons. Parsons was a second-round pick out of Florida in the 2011 draft.
Dallas got an agreement in place with Parsons even before small forwards Carmelo Anthony or LeBron James announced where they will play, a signal that the Mavericks are most likely out on the two most prominent free agents.
Anthony visited the Mavericks at the start of the free agency period, but Dallas owner Mark Cuban has acknowledged that he couldn't offer the forward a max contract.
Parsons averaged 16.6 points, 5.5 rebounds and 4.0 assists last season for the Rockets. He has played 213 games, starting 207 of them, while averaging 14.1 points, 5.2 rebounds and 4.1 assists.Comment on this story
In Dallas, he would be in a frontcourt with Dirk Nowitzki and recently reacquired Tyson Chandler.
Nowitzki and point guard Devin Harris have already agreed on new contracts that will be able to be signed as early as Thursday. Chandler, part of the Mavericks' only NBA title in 2011, rejoined Dallas in a trade from the New York Knicks.
Shawn Marion, the primary small forward for Dallas the past five seasons, is a defensive specialist and unrestricted free agent.
