CHICAGO (AP) Chicago Bulls forward Paul Shirley will miss the rest of the season after bruising his kidney in Monday night's loss to the Pacers.

Shirley was hospitalized when the Bulls returned from Indianapolis and remained there Tuesday, Bulls coach Scott Skiles said. X-rays were negative.

``He was in a lot of pain. It was a bad flight for him. It was a struggle,'' Skiles said. ``We were worried about him for sure.''

The 6-foot-10, 230-pound Shirley was injured with 5:34 left Monday night after a collision with the Pacers' Austin Croshere.

Shirley joined the Bulls from the ABA's Kansas City Knights and signed two 10-day contracts, the second one March 15. He averaged three points in seven games with Chicago.
