Pro wrestling legend Sting is hanging up his boots after Sunday's big match at AEW Revolution ... a moment so special, tag team partner Darby Allin says it's actually the highlight of his young, but impressive, career -- and he's not even the dude retiring!
"Oh, without a doubt. Without a doubt, it's the biggest [match of my career]," Allen told us, adding, "He's been around longer than I've been alive. Like on top of the wrestling. It's really cool to be a part of it and definitely my biggest match and I'm not taking anything for granted.
