LaMarcus Aldridge and Gerald Wallace each scored 15 points for the Trail Blazers.
Spurs 122, Magic 111
Dwight Howard lost perhaps his last game with Orlando, declaring before a loss at San Antonio that he won't surrender his right to become a free agent this summer.
Howard had 22 points and 12 rebounds on the eve of the NBA trade deadline, and his refusal to give the Magic the ultimate assurance that he will be back may weaken Orlando's hesitation to trade their superstar.
The trade deadline is 3 p.m. Thursday.
Tony Parker had 31 points and 12 assists and Tim Duncan had 21 points and 13 rebounds as the Spurs closed a seven-game homestand by hosting the NBA's biggest drama.
Parker, averaging 29.8 points in his last four games, was serenaded by chants of "M-V-P! M-V-P!" in the closing minutes.
Nets 98, Raptors 84
Kris Humphries had 16 points and a career-high 21 rebounds to lead New Jersey to a win over Toronto in Newark, N.J.
Former D-League star Gerald Green tied his season high by scoring 20 of his 26 points in the second half as the Nets snapped a two-game skid. Anthony Morrow added 15 points for New Jersey.
James Johnson and Jerryd Bayless had 16 points apiece for Toronto, which was limited to 38 second-half points, including 15 in the third quarter, when the Nets took the lead.
New York Knicks coach Mike D'Antoni resigned, surprising even his bosses.
"It wasn't just Carmelo [Anthony]," interim general manager Glen Grunwald said. "I think it was our whole team was not playing up to where we thought they could be and I know Mike was as frustrated as anyone about that, and that's what led him to that decision, that maybe there needs to be a new approach and look at it."
Assistant Mike Woodson is serving as interim head coach.
The Knicks' brief resurgence in a wave of Linsanity last month has been replaced by a six-game losing streak that has dropped them into a tie for the eighth and final playoff spot in the Eastern Conference.
