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

Peyton’s kids are said to be safe and healthy, according to the report.

“I just wanted to let everyone know on Razorback Nation that Peyton is doing better,” 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!!!”

Hillis was in Pensacola, Fla. when the accident happened, and he was airlifted to the hospital and remains in the ICU.

The 36-year-old Hillis had a seven-year NFL career that spanned from 2008-14. He played for the Broncos, Browns, Chiefs and Giants after being drafted out of Arkansas by Denver in the seventh round. Known for his bruising style of play as a running back, his best year came for the Cleveland Browns in 2010. That season, Hillis carried the ball 270 times for 1,177 yards and 11 touchdowns. He also caught 611 passed for 477 yards and two touchdowns that season.

The stellar year earned him cover honors for the “Madden ’12” video game.

He finished his career with the Kansas City Chiefs, where he retired following multiple nagging injuries.
