Tracy McGrady came in for treatment on his back Sunday feeling "very stiff and very sore," Rockets trainer Keith Jones said.

But McGrady responded to treatment, a good sign. Jones said McGrady was sent home with anti-inflammatories and muscle relaxers and instructions to stretch and exercise, but could not predict whether McGrady could play Tuesday.

"With his back, he could come in tomorrow and feel better," Jones said. "He could feel worse. You just don't know."
