Buakaw Banchamek is headed to the bareknuckle boxing world.

The muay Thai superstar has signed a multifight deal with BKFC and is already scheduled to debut for the promotion Sept. 3 in Thailand against an opponent yet to be determined.

The news was announced by the promotion Wednesday.

Banchamek is considered by many as a living legend and one of the greatest muay Thai fighters of all time. He has an incredible record of 240-24-12 with 73 finishes.

He’s also a two-time K-1 champion and six-time world muay Thai champion. The 40-year-old Banchamek has been fighting professionally since 1999. He was most recently seen in action earlier this month when he picked up a decision win over Dmitry Varats.
