Former NFL running back Peyton Hillis is reportedly hospitalized after a swimming accident where he saved his kids from drowning, according to TMZ.

According to the report, Peyton remains in the intensive care unit for treatment on his lungs and kidneys, but doctors say his health is improving, according to his uncle, Gregg Hillis. Peyton’s kids are said to be safe and healthy, according to the report.

According to Fox’s 24 reporter Alyssa Orange, Peyton Hillis was in Pensacola, Fla. when the accident happened and he was helicoptered to the hospital and remains unconscious in the ICU.

While there were posts on social media indicating that Hillis was in critical condition, his uncle, Greg Hillis, wrote on Facebook that his nephew’s conditions were improving.

“I just wanted to let everyone know on Razorback Nation that Peyton is doing better,” Greg Hillis wrote. “He’s still in intensive care and having some problems with his kidneys and his lungs but the doctors say he is improving. I just wanted to head off any rumors that may be started. I’m sure he would want everyone to know that he appreciates all of the prayers thrown up on his behalf!!!”
