Raymond Felton struggled to get dressed, wincing every time he had to use his swollen left hand, which wasn't a good sign for the Knicks.
"It hurts," Felton said.

Felton jammed his thumb while trying to dribble through a screen late in the Knicks' 106-99 victory over the Suns Sunday. He finished the game, but an MRI revealed a contusion and bone bruise.
The Knicks are listing Felton as day-to-day. They are off until they open a three-game road trip in Charlotte on Wednesday.
"It's swollen right now," Felton said. "It's a lot of pain. We'll see what happens."
The Knicks are keeping their fingers crossed that it isn't anything too serious. Mike Woodson was seen talking to Felton before he came into the locker room to get dressed.
Felton is the Knicks' second-leading scorer (15.1 points) and is averaging a team-high 6.8 assists. He finished Sunday with 23 points, seven assists and no turnovers.
The Knicks already are without Jason Kidd. He worked out and shot around before tipoff but missed his fourth straight game because of lower-back spasms. They hope he can return during the trip.
Woodson said Kidd's minutes will be restricted when he comes back. It appeared likely that Kidd would return Thursday at Miami, the second game of a back-to-back. But that was before Felton got hurt.
Pablo Prigioni had been playing more minutes in Kidd's absence, but he played only about nine minutes Sunday. Prigioni suffered a bloody nose after being smacked in the face by Sebastian Telfair, but it wasn't serious.
Felton said if it's up to him, he will play. The injury is to his non-shooting hand, but he has the ball so often, it's going to get hit.
"I finished the game with it without it wrapped," Felton said. "With it wrapped, it should be fine."
