Friends of Alex Karras say the former Lions great suffered kidney failure in the last two weeks and has been given only a few days to live.
Tom McInerney, owner of McInerney’s Woodhaven Chrysler Dodge Jeep Ram and a friend of Karras’ since the 1950s, said Karras’ wife, Susan Clark, told him of her husband’s failing health in a 15-minute phone call this morning.
“I got a call from Susan last Wednesday or Thursday that he was in the hospital,” McInerney said. “(His kidneys) gave out on him and legs swelled up and his ankles swelled up and arms, so she said it doesn’t look good. They figured probably a couple weeks.
“He said, ‘I want to go home,’ so knowing Alex she made arrangements for him. She talked to me Saturday morning waiting for the ambulance to take him home with her daughter and she was going to let me know. Well, I couldn’t get in touch with her yesterday or Saturday and she called me this morning, said, ‘It doesn’t look too good, Tommy. They’re talking probably a couple days.’
