Bob “Blackjack Mulligan” Windham, who has had a number of health issues in recent years and was scheduled to undergo brain surgery today to help relieve pressure on the brain, suffered a heart attack yesterday after being hospitalized.

72-year-old Windham is currently in a critical condition, but is awake.

On behalf of Wrestling-News.Net, we would like to send our best wishes to Mulligan and wish him a quick recovery.
