A day after Lou Williams took a scary fall in Saturday's 105-77 victory against the New York Knicks at Madison Square Garden, the 76ers point guard was officially sore.

Williams was clobbered by Knicks forward David Lee while driving to the basket with 3 minutes, 30 seconds left in the third quarter.

Lee was charged with a "flagrant foul 1," which gave the Sixers two free throws and the ball. The third-year player made 1 of 2 free throws and left the game for good.

After the game, Williams said he felt fine after landing on his neck and shoulder, although he said he felt dizzy immediately after the foul. He was reevaluated yesterday by the Sixers' medical staff.

"Both his head and neck checked out OK," said Michael Preston, the team's public relations director. "We are expecting him to play [tonight] against Houston."

The Sixers, who beat the Knicks in two straight for their first consecutive wins this season, host Yao Ming and the Rockets at 7 at the Wachovia Center. The Rockets are 11-10 after yesterday's 93-80 loss in Toronto.

Williams underwent treatment on his shoulder and neck yesterday, according to his agent, Merle Scott. Williams did not return a phone call for comment.

"He is doing pretty well," Scott said in a telephone interview. "He was a little concerned when it happened but realized that he was OK and was a little sore."

The guard, who has shown no fear when taking the ball to the hoop, is not about to alter that approach, Scott said. "He said that wasn't going to stop him from going to the basket and being aggressive."

Williams scored seven points Saturday after tallying 15 in Friday's 101-90 victory over the Knicks.

He has provided a major spark off the Sixers' bench. Williams is averaging 11.1 points and is the team's top three-point shooter (18 for 40, 45 percent). He also is averaging 3.5 assists and 1.7 turnovers.

In the paint. The Sixers were dominant inside in both games against the Knicks. Samuel Dalembert and Reggie Evans outrebounded New York's Eddy Curry and Zach Randolph by 40-14 in the sweep.

Evans had 14 rebounds Saturday despite being bothered by a sore right shoulder.

"I have to tough it out and play through it," Evans said. "It might mean sitting out sometimes in practice, but I'll be all right."

The Sixers' psyche also seems to be improving after their most productive weekend of the season. A cynic would suggest that their two-game streak came against the 6-13 Knicks. Still, it was a Knicks team that had won four of its previous six games.

Andre Iguodala, who scored 17 points Saturday, put the weekend in perspective.

"It's always good to win back-to-back, but I don't think the Knicks played their best basketball, so we still have room for improvement," Iguodala said. "We will take these two and keep moving."
