Augusto Sakai will attempt to keep his unbeaten record intact when he faces Dan Charles in a featured heavyweight bout at Bellator 155.
Promotion officials announced the contest on Thursday. Bellator 155 takes place at CenturyLink Arena in Boise, Idaho, on May 20 and is headlined by a 185-pound title clash between reigning champion Rafael Carvalho and Melvin Manhoef.
Sakai won his fourth bout with the California-based promotion this past November, as he outpointed Alex Huddleston at Bellator 145. The 24-year-old Brazilian has finished seven of his nine career triumphs by knockout or technical knockout.
