Shawntinice Polk, center on the University of Arizona's women's basketball team, died Monday after collapsing on the court of the school's arena.

Richard Paige, associate media relations director, said Polk, 22 and a senior, was not working out or practicing in McKale Center when she collapsed.

Polk was taken to the University Medical Center, where she was later pronounced dead. The cause of death was not immediately known and an autopsy will be performed.

Coach Joan Bonvicini, who had been out of town, returned to the campus to meet with the team.

"This is a terribly sad, heartbreaking day in Arizona women's basketball," Bonvicini said. "I can't put into words the pain and sadness that we're all feeling right now."
