Wide receiver Tyjon Lindsey and defensive lineman Dylan Owen were hospitalized after a winter workout last week, but have been released and have returned to the team, Nebraska head coach Scott Frost confirmed to the Journal Star on Tuesday morning. Lindsey and Owen both were treated for rhabdomyolysis, the first-year Husker head coach said. Lindsey was in the hospital for three days and Owen for two. "Anything that happens in our program is ultimately my responsibility," Frost said. "Our strength coach and training room were coordinating to do absolutely the best they could to make sure the transition went smooth, but two kids that exerted themselves too far and had (rhabdomyolysis). "I want to make sure people understand that the health of our players is always going to be our primary concern. It's been kind of a scary deal and both kids are doing fine now." Rhabdomyolysis is a muscle injury that, "results from the death of muscle fibers and release of their contents into the bloodstream. This can lead to serious complications such as renal (kidney) failure. This means the kidneys cannot remove waste and concentrated urine," according to a WebMD description of the disorder. The condition can become serious or even life-threatening if kidney function is significantly impacted. Frost said that in each Lindsey and Owen's cases, the multiday hospital stays were mostly precautionary.
