7:50pm: Furkan Aldemir is headed to Philadelphia as well, tweets Keith Pompey of the Philadelphia Inquirer, identifying the international prospect in the deal.
7:02pm: The Rockets have agreed to trade Royce White to the Sixers, according to Adrian Wojnarowski of Yahoo! Sports. Houston will receive future draft considerations from Philadelphia, and the Rockets will throw in the draft rights to an international prospect as well as cash.
White, the 16th pick in the 2012 draft, never appeared in a regular season game for the Rockets because of his battles with the team concerning accomodations for his psychological disorders. He averaged 11.4 points and 5.7 rebounds in 16 games for the Rio Grande Valley Vipers, Houston's D-League affiliate.
The move clears White's $1,719,480 guaranteed salary from Houston's books, though as HoopsWorld's Eric Pincus points out (on Twitter), the Rockets still probably need to clear a little more room to fit in a max contract for Dwight Howard. That could entail simply cutting one of a few players on a non-guaranteed deal. Greg Smith, James Anderson, Patrick Beverley and Tim Ohlbrecht all have deals that aren't fully guaranteed, though Beverley would figure to be the least likely among them to go.
