Second-year small forward Dan Langhi returned to the Rockets 12-man active roster, reports Jonathan Feigen of the Houston Chronicle.  Langhi had been on the injured list with a sprained ankle for the first 10 games of the season.  Guard Tierre Brown was put on the injured list in Langhi's stead.  After his minimum 5-game stay on the injured list, Langhi's agent publically requested a trade for his client to a team where he could get more playing time.  The Rockets have Glen Rice, Walt Williams and rookie Terence Morris playing the same position.
