The family of former Super Bowl-winning running back Ronnie Hillman announced that he died from a rare form of kidney cancer at 31.
On Wednesday, the former Denver Broncos player's family said on his social media account that he'd be diagnosed with renal medullary carcinoma in August and had been placed into hospice care, the Associated Press reported.
A few hours later, the news outlet reported that his family announced on social media that Hillman had died while surrounded by family and close friends.
The Broncos, who drafted Hillman in 2012, took to Twitter to express their condolences.
