Buddy Ryan Has Cancer: Rex Ryan Says 'He Should Be All Right'

New York Jets coach Rex Ryan told the New York Daily News on Tuesday that his father, former NFL coach Buddy Ryan, has been diagnosed with cancer.

According to the report, Ryan didn't say specifically what type of cancer his father has. Buddy was reportedly diagnosed "a couple of weeks ago."

"He's 80 years old, but he's doing great. He's tougher than s---," Rex Ryan said. "He's had other things in his life. He overcame encephalitis. He's overcome cancer twice. He's tough."

Buddy was the defensive coordinator for the Chicago Bears team that won Super Bowl XX. He became head coach of the Philadelphia Eagles the following season and also coached the Arizona Cardinals.
