MANILA, Philippines – Chael Sonnen snapped a two-fight losing streak in impressive fashion as he submitted former UFC light heavyweight champion Mauricio “Shogun” Rua in the main event of UFC Fight Night in Boston. Sonnen, who lost to Anderson Silva and Jon Jones in back-to-back title fights, took the Brazilian Rua down just seconds into the fight. With 30 seconds left, Sonnen was able to trap Rua in a guillotine choke, and the former champion tapped at the 4:47 mark of the very first round. -- Mornings @ ANC, ANC, August 19, 2013
