Markman wrote that Ditka "wanted everyone to know he's ok." Ditka did not immediately return a message from The Associated Press.
He told the Chicago Tribune he was feeling "good right now and it's not a big deal." He was playing cards at a suburban country club Friday when he noticed his hands "weren't working quite right," and he then started having difficulty speaking.
The 73-year-old Ditka had a heart attack during the 1988 season when he was coaching the Bears.
The stroke came on the same day that a Lake County prosecutor said in court that Ditka's son, Mark E. Ditka, tested positive for opiates during a pretrial screening earlier this month, according to the Tribune. The younger Ditka is awaiting trial on his fourth DUI charge.
