Hillis was at a Pensacola beach when he rescued two of his children from drowning on Wednesday. He needed to be airlifted to a local hospital, as he was experiencing lung and kidney damage. 

"I just wanted to let everyone know on Razorback Nation that Peyton is doing better," Hillis' uncle, Greg, said in a Facebook post last week. "He’s still in intensive care and having some problems with his kidneys and his lungs but 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 being thrown up on his behalf!!!"

Though he didn't make the Pro Bowl that season, he was rewarded by being the cover athlete of Madden NFL 12.

He spent the 2012 season with the Kansas City Chiefs before spending his final two seasons with the New York Giants.

While at Arkansas, Hillis played a key role as a pass-catching back. In fact, he had more receiving yards (1,197) than rushing (960) in his four years there – a dozen of his 23 touchdowns came from the ground.
