Former Iowa football star Brett Greenwood is in an Iowa hospital after collapsing during a workout.
A spokeswoman for Trinity Medical Center in Bettendorf says Greenwood was taken there in critical condition Friday. He's since been transferred to University of Iowa Hospitals and Clinics in Iowa City, Iowa. That hospital said it could not provide any information.
The Quad-City Times in Davenport, Iowa reported Greenwood suffered an apparent heart attack and then collapsed while working out at Pleasant Valley High School in Bettendorf, Iowa. Athletic director Randy Teymer told the newspaper that school medical personnel treated him before he was taken by ambulance to Trinity Medical Center.
According to the report, Pleasant Valley team trainer Jason Viel was the first to reach Greenwood and told the paper he thought it was a heart attack.
"That's just an assumption," said Viel, who added that it took only one shock from a defibrillator to restore a pulse. "Basically, his heart stopped. I know that."
The 23-year-old Greenwood was a four-year starter at safety for Iowa and was named second-team All-Big Ten each of the past two seasons. He signed as a free agent with the Pittsburgh Steelers, but was released in the final round of NFL cuts last weekend.
