Choo Sung-hoon is doing a rematch with Chris Leben?

His last fight in Bare Knuckle was back in '21, but
given Choo Sung-hoon's age to begin with,
if he's trying to live up to his name, it's a bit much to expect him to be in his absolute prime.
However, since the opponent involves a sense of revenge, it feels reasonable.
I was really disappointed about the rematch,
but even though Leben is younger, he doesn't look to be in great shape right now lol
