Bob "Blackjack Mulligan" Windham was scheduled to undergo brain surgery today to help relieve pressure on his brain but PWInsider.com is reporting that Blackjack had a heart attack yesterday.
The 72-year-old WWE Hall of Famer (class of 2006) is the father of Barry Windham and the grandfather of WWE stars Bray Wyatt and Bo Dallas - their dad and Blackjack's son-in-law is Mike Rotunda, who you might know as Irwin R. Schyster or I.R.S.
Windham is currently in critical condition.
