It's boxing vs mixed martial arts all over again.

Dream Lightweight Champion Shinya Aoki will meet former WBA Super Flyweight Champion Yokthai Sithoar at DEEP 50 on Oct. 24. The organization confirmed the bout at a recent press conference (via Chris Nelson).

The event will celebrate the 10 year anniversary of DEEP.

After suffering defeat in his U.S. debut to Strikeforce Lightweight Champion Gilbert Melendez back in April, "The Tobikan Judan" went back to Japan and claimed back-to-back victories. Aoki submitted Tatsuya Kawajiri at Dream 15 in July and defeated Marcus Aurelio by decision at Dream 16 in September. 

Sithoar, a former WBA boxing champion, will be making his mixed martial arts debut in this bout.

The former Thailand boxer racked up a 29-6-3 record with 18 KOs as a pro. Sithoar retired from boxing in 2004 after going 0-3-2 in his last five fights, leaving the sport without a win since early 2003.

DEEP 50 takes place from the JCB Hall in Tokyo, Japan, on Oct. 24.
