"Melo was hurt," Woodson said. "For him to ask me to come out of the game before he actually took that spill made me realize that something wasn't right. He's never ever, ever, even hinted about coming out of the game. I play him too much in that regard. Melo's a trooper - he's a warrior, he's a tough kid.
"Maybe I should have taken him out before he actually stumbled and took the fall. But again, I'm thinking [during] the game, 'Hey, he'll play through it. He'll figure it out.'
"But he was hurt. He walked out after he took the spill and he didn't come back, and that's not Melo-like. Obviously, his knee is bothering him."
Oklahoma City forward Serge Ibaka was fined $25,000 by the NBA for striking Blake Griffin of the Los Angeles Clippers in the groin area during Sunday's game.
The league also upgraded the flagrant foul 1 Ibaka's was given for hitting Griffin as the two battled for position in the paint to a Flagrant-2 foul, meaning Ibaka should have been ejected from the game.
The incident occurred with 1:52 remaining in the fourth quarter.
* Aaron Brooks returned to the Houston Rockets and it's a completely different lineup from when he left 2 years ago.
The 6-foot Brooks rejoined the team that drafted him in 2007.
To make room for Brooks, the Rockets waived forward Tyler Honeycutt, who was acquired from Sacramento in a multiplayer trade just before the deadline. Houston picked up rookie Thomas Robinson and Francisco Garcia in that deal and now add Brooks, who averaged eight points and 2.3 assists in 46 games for the Kings this season.
Brooks played his first 3 1/2 NBA seasons in Houston and was traded in February 2011. None of Brooks' Houston teammates from then are there now.
* The NBA has downgraded a Flagrant-2 foul on Minnesota Timberwolves guard J.J. Barea to a Flagrant-1.
On Sunday, Barea was ejected in the fourth quarter against Miami after a foul on Heat guard Ray Allen. Barea knocked Allen to the court with a chest bump and Allen immediately took exception and confronted Barea. Officials initially ruled it a Flagrant-1 which gives the opponent two shots and the ball.
Upon reviewing the play, referee Ed Malloy changed it to a Flagrant-2, which brings an automatic ejection. Barea said he is pleased with the league's decision.
* A federal judge in Dallas denied a request by Mavericks owner Mark Cuban to throw out a civil lawsuit accusing him of insider trading.
U.S. District Judge Sidney Fitzwater issued an order rejecting Cuban's request for summary judgment against the Securities and Exchange Commission.
The SEC accused Cuban in 2008 of selling shares in Internet search company Mamma.com after receiving confidential information about a private stock offering at a discounted rate. The SEC's lawsuit says Cuban avoided losses of more than $750,000 by selling when he did.
