A previously announced bout pitting Roger Gracie against Michal Pasternak at Vitaly Bigdash and Alexey Butorin was removed from the card. One Championship 41 “Ascent to Power” takes place at Singapore Indoor Stadium in Kallang, Singapore, on May 6 and features an atomweight title tilt between Angela Lee and Mei Yamaguchi.
Gracie will be competing for the first time since scoring a third-round TKO win over James McSweeney in his promotional debut in December 2014. The former UFC and Strikeforce talent is 7-2 as a professional with wins over the likes of Keith Jardine, Anthony Smith, Kevin Randleman and Trevor Prangley.
