TAMPA, Fla. (AP) - South Florida running back Keeley Dorsey collapsed and died Wednesday after a team conditioning workout at the school's athletic facility.

The 19-year-old freshman died at University Community Hospital, South Florida said in statement.

Dorsey, a graduate of Tallahassee Lincoln High School, rushed for 68 yards on 10 carries in 2006. He scored his only touchdown on a 52-yard run on the final play of the Bulls' 41-10 season-opening victory over McNeese State.

It was South Florida's longest run of the season.

"I hurt for Keeley. I hurt for Keeley's parents. I hurt for our team," coach Jim Leavitt said in a statement. "Keeley was a tremendous person. He was always upbeat and an inspiration to me and all of us. He had a great impact on our team, and he will be sorely missed."

Leavitt was in West Palm Beach on a recruiting trip and returned to campus to join his players.

"Our entire athletic family is deeply saddened by this tragic loss," athletic director Doug Woolard said, adding that Leavitt had spoken with Dorsey's father.

Dorsey was given first aid before he was transferred to the hospital, the school said. A hospital spokesman did not immediately know Dorsey's condition when he arrived.

"The USF community is extremely shocked and saddened by the death of one of our student athletes on campus today," USF President Judy Genshaft said. "There is nothing more tragic than the loss of one of our students, and our thoughts and prayers go out to Keeley's family, friends and fellow athletes and students."
