Pele Reid has that KO win over in Klitschko in KB !

There's been a few Glory kickboxers that have dabbled in Boxing. Nicky Holzkien, and there was one that fought recently. I forget his name at the moment, but he was a big name in Glory.

Ricardo Mayorga tried his hand at MMA

If you'd count Bareknuckle as a separate sport, then there's a lot of Crossover in the guys that compete in that. Paulie Malignaggi and Austin Trout are the most notable boxers I know of that have tried it.

Ray Mercer had a handful of MMA fights.

Gary Goodridge had numerous MMA fights, and a few Kickboxing matches.

Almost any Boxer out of Thailand has probably had at least a few Muay Thai bouts as well.

Was semi contact and and I think it was an illegal shot. But yeah he did um get the KO! But under dodgy circumstances
