76-year-old WWE Chairman and CEO Vince McMahon just wrestled WWE commentator, sports analyst and former professional football player Pat McAfee in an official -- albeit unannounced -- WrestleMania match.During the second night of WrestleMania 38 in Dallas, McAfee was booked to wrestle Austin Theory, the latter of whom had Mr. McMahon in his corner. McAfee ultimately defeated Theory, much to McMahon's chagrin -- and things only got more chaotic from there.RELATED: WATCH: Triple H Bids Farewell to In-Ring Competition at WrestleManiaMcMahon took to the ring to challenge McAfee to a match himself, with the chairman of the board even kicking things off by hitting his opponent with a clothesline. Following some underhanded interference by Theory, McMahon defeated McAfee, kicking a Dallas Cowboys-branded football into his ribs before pinning him for the three count.

While he is best known as an executive and on-air personality, McMahon has actually stepped into the ring on a number of occasions during his multi-decade tenure as the head honcho of WWE. That being said, before 'Mania 38, he had not wrestled in an official match since his loss to Bret "The Hitman" Hart at WrestleMania XXVI in 2010 (when McMahon was 64).

However, McMahon and Theory's victory celebration was cut short when McMahon's longtime rival Stone Cold Steve Austin came out and stunned the both of them. Austin then proceeded to celebrate with McAfee... before stunning him as well. It was on the first night of WrestleMania 38 that Austin himself briefly came out of retirement to wrestle his first match since WrestleMania XIX in 2003, ultimately defeating Kevin Owens.
