Ditka was hospitalized Friday after he noticed, while playing cards with friends, his hands "weren't working quite right" and he had a problem speaking.
"I feel good right now and it's not a big deal," Ditka said, according to The Chicago Tribune.
Ditka, 73, hasn't had any major health problems in recent years, but "Iron" Mike did have a heart attack in 1988 while coaching the Bears. He was back at work within a week, which sounds kind of familiar.
According to an ESPN NFL producer, Ditka will not work this weekend's games from the studio.
