Detroit Pistons rookie center Andre Drummond did not play the second half of a 99-85 loss tonight to the New York Knicks because of a back injury suffered in a game Sunday.

Drummond played just eight minutes in the first and second quarters, then did not return.

He said the injury occurred when he tried to block a shot by the Los Angeles Lakers' Steve Blake and twisted as he landed.

"Just a bad landing and I tweaked it a little bit," he said.

Playing the second day of a back-to-back didn't help and Drummond said he never managed to get the back loosened up against the Knicks.

"It's tough, you know, hotel beds," he said.

Drummond said his current pain is unrelated to a back injury he suffered this summer and that he expects to play in Wednesday's home game against the Brooklyn Nets.

"Just a bad landing, that's all," he said. "It happens. You never know when these things come up. I just have to take care of it and I'll be all right. I'll be ready for Wednesday."
