ADCC 2017, Day 2 results: Chael Sonnen defeats Leo Vieira

Bellator light heavyweight Chael Sonnen won his superfight in the second day of Abu Dhabi Combat Club (ADCC) Sunday in Espoo, Finland.
The former UFC title challenger took on two-time ADCC 145-pound champion Leo Vieira. The jiu-jitsu ace replaced Frank Mir (who replaced Ricardo Liborio in the first place) against a much heavier Sonnen. Neither fighter did much over the course of the match, and Sonnen ended up winning a referee decision after no points were scored in 15 minutes.
