Almost a week after 13 University of Iowa football players were struck down with the muscular syndrome rhabdomyolysis, every one of them has been released from the hospital, the team announced Sunday.

All 13 were taken to the University of Iowa Hospitals and Clinics on Monday with the condition, which can cause serious kidney problems. It was developed following intense offseason workouts.

Five of the players were released Friday, another six Saturday and the final two Sunday.

"Getting all 13 student-athletes healthy and out of the hospital has been priority number one all along, so I'm very happy that they all are now back home and resuming their lives," Iowa coach Kirk Ferentz said in a statement.

Rhabdomyolysis can be exacerbated by cocaine or methamphetamine use, but tests for illegal drugs were negative on all 13 players.

Though the drug tests ruled out those two substances, they did not rule out over-the-counter supplements as a possible cause.

The players were reportedly put through a 100-squat weightlifting routine, which several former Hawkeyes said they were familiar with.
