Well, this may be a first. Mid-way through the fight, Claudinei Angelo (4-5) would lose his bout to Evilasio Silva (8-12). The odd part of the victory is Silva wins due to Angelo leaving the cage. Perhaps the recent death in the sport (in Brazil) caused the fighter to weigh on the side of caution.
The reports coming in are that Angelo was poked in the eye numerous times in the bout. Frustrated with the lack of officiating, he left the cage, forfeiting the fight.
