Tyrone Spong knocked out kickboxing legend Remy Bonjasky with a thunderous right hand in the second round of the Glory 5: London main event on Saturday at ExCel Arena.

Spong, who made his mixed martial arts debut in November at World Series of Fighting 1, pressured Bonjasky the entire fight, walking him down and not giving him space to work his world famous kicking game.

The knockout came at the 2:02 mark of the second round. Spong had Bonjasky in the corner and delivered a left hook counter to the chin of Bonjasky rendering him unconscious.

Ive put in a lot of work, hard work, and I know what Im capable of, so I wasnt surprised, said Spong following the win. I just took my time. I had three rounds and I took it easy.

Spong knocked out another kickboxing legend, Peter Aerts, in his last kickboxing bout, and is looking for bigger challenges ahead. Hed like to face Semmy Schilt next.

I like challenges, and Im just looking forward to fighting the best, so give me Semmy. Give me whoever, he said.

Bonjasky was left wondering what his future holds in a sport that hes already accomplished so much.

It was pretty tough. I mean a three-year absence, three fights. Its hard when youre 37 and trying to make a comeback, said Bonjasky after the loss. Its hard to make a good comeback. My comeback has been rocky. I did my best. Ive done everything, but my body says its hard.
