Sherdog.com confirmed the booking with a promotion official following an initial report from MMAjunkie.com. Bellator 254 takes place on Dec. 10 at Mohegan Sun Arena in Uncasville, Connecticut, and is headlined by a flyweight championship tilt between Ilima-Lei Macfarlane and Juliana Velasquez.
Yamauchi enters the matchup with Andrews having won six of his last seven promotional appearances. Most recently, the 27-year-old Japan native choked out Daron Cruickshank at Bellator 237 last December. Yamauchi is 11-3 over the course of his Bellator tenure.
Andrews, 36, won nine consecutive fights with CES MMA before a recent 1-2 stint with Professional Fighters League. Andrews concluded his 2019 PFL season with a majority decision loss to Chris Wade in the playoffs last year. “The Snake” is 16-3 as a professional, with all but one of his victories coming inside the distance.
