The Knicks injury-wracked preseason couldn't get worse, could it? It could and it did.

"Thank God exhibition is over,'' coach Mike Woodson said Wednesday night.

Amen. It was capped by Tyson Chandler's left-knee injury after a spill 44 seconds into the game after he banged into Gerald Wallace while setting a screen, took a tumble and missed what turned into a meaningless 97-95 overtime preseason finale victory over the Nets at the soldout Nassau Coliseum.

Chandler will have an MRI exam Thursday. He left the locker room on crutches, but said he believes it's just a knee sprain and not an ACL tear. Nevertheless, even if it's just a sprain, it is disheartening because it could put Chandler out for the season opener in one week in Brooklyn against these Nets, joining Amar'e Stoudemire and possibly Marcus Camby on the shelf. Knee sprains can take up to one to two weeks to heal.

"I am just hoping that it is not much, so I can continue to work with the guys leading up to the first game,'' Chandler said, crutches by his side in the locker room. "I felt great before the game. I was excited. I was up for this game to set tempo moving into the first game of the year and I play 44 seconds.''

Asked what happened on the play, Chandler said, "I stretched my knee out a little and it was awkward. My foot was planted when he fell into me and it took my knee outside. I did not feel it until I landed. They told me to stay off the knee until I get an MRI.''

Asked his level of concern, Chandler said, "Not much,'' but his spirits seemed down.

The Knicks won despite Carmelo Anthony scoring just 15 points on just 4 of 13 shooting and three turnovers.
