Rockets Coach Rudy Tomjanovich has a cancerous tumor on his bladder lining that the team said will be treated without surgery.

The 54-year-old coach was released from the hospital and was resting at home, the Rockets said yesterday.

Team physician James Muntz said Tomjanovich has "transitional cell cancer of the bladder." The coach will begin weekly treatments in two weeks, but Muntz did not specify the nature of the treatments.

"Rudy's treatment options are optimistic," Muntz said following a biopsy of the bladder lining on Monday.

Tomjanovich was to miss last night's game at Seattle. Assistant Larry Smith will coach the team in his absence.

After recovering from a bladder infection about a month ago, Tomjanovich said he went in for routine follow-up tests, the second of which turned up abnormal cells.

Hill's heel was reshaped to realign his left leg during the operation at Duke Medical Center in Durham, N.C. Surgeons also removed three screws from previous surgery as well as some bone.
