DETROIT (AP) - Detroit Lions president Tom Lewand says the franchise is deeply saddened to learn of Alex Karras' condition.

The 77-year-old Karras has been suffering from dementia. He is among the many former NFL players suing the league regarding the treatment of head injuries.

Detroit drafted Karras out of Iowa in 1958 and he was a standout for 12 seasons. He may be even better well known for his work as an actor. He played the role of Mongo in the 1974 comedy classic "Blazing Saddles," and was a lovable father in the 1980s sitcom "Webster."
