Former pro wrestler Blackjack Mulligan is dead at age 73, World Wrestling Entertainment announced Thursday.
"WWE is saddened by the news that Robert Windham, aka WWE Hall of Famer Blackjack Mulligan, has passed away," a statement said.

He wore all-black, including a cowboy hat and leather glove, and was part of the 1975 world champion tag team The Blackjacks with Blackjack Lanza.
According to The New York Daily News, Windham retired in 1987.
The Blackjacks were inducted into the WWE Hall of Fame together in 2006.
He most recently made headlines in a 2015 lawsuit against the WWE for concussion-related injuries. Marine and played football for the New York Jets and the University of Texas at El Paso. Windham's grandsons have carried on the family wrestling legacy as Bray Wyatt and Bo Dallas.
He told the AP he had been diagnosed with dementia and blood clots in his brain, blaming head trauma suffered in the ring, including when he was beaten unconscious by Sargent Slaughter. Windham's survivors include former pro wrestler sons Barry Windham and Kendall Windham, who wrestled for the NWA, WCW and WWF, and his son-in-law Mike Rotunda, who was a varsity wrestler at Syracuse University. Dallas became the youngest NXT Champion in WWE history at age 23 in 2013, and Wyatt has found success as the leader of "The Wyatt Family," featuring himself, Luke Harper and Erick Rowan.
Rotunda won the EIWA Championships in 1981 as a Heavyweight, before becoming a WWE wrestler known as Irwin R.

The authorities found close to $500,000 in phony $20 bills.
As a result of a plea agreement both father and son spent 24 months in a federal prison and were released in 1992.
