2:56pm: Christmas confirmed on his Twitter account that he'll be signing with the Rockets, tweeting, "It's official Ill be a member of the Houston rockets!…#footinthedoor." No word yet on the corresponding roster move.
2:30pm: The Rockets are close to a deal with former Temple guard Dionte Christmas, a source tells Emiliano Carchia of Sportando (Twitter link). Sportando first passed along a report out of Greece that Christmas was close to signing with the Rockets.
Christmas, 25, graduated from Temple in 2009 and played in the NBA Summer League in 2009 and 2010 for the 76ers and Kings, respectively. While he was signed by Philadelphia in '09, Christmas was cut by the Sixers before the regular season began, and has never played an NBA game. Over the last few years, he has played for a variety of teams overseas, including Greece's Rethymno B.C. this past season.
If the Rockets do bring Christmas aboard, it would be a slightly surprising move. With only one game left in the season, Houston would presumably be hoping to get a look at Christmas over the summer, perhaps agreeing to a non-guaranteed deal for next year. The team's roster is full at 15 players though, so the Rockets would need a corresponding move to make room for a new addition.
