Get used to the name of Cully Butterfield. Known as "The Mason", Butterfield went into hostile territory on Saturday night and delivered the biggest performance of his young career by knocking off Egidijus Valavicius in the main event of Flawless Fighting Championship "Hated".

Training out of Roufusport in Milwaukee, Butterfield has made great strides since turning professional back in May of 2009. And following his unanimous decision upset over Valavicius in Chicago, the UW-Milwaukee student has emerged as one of the state's brightest light heavyweight prospects.

Entering into Saturday's FFC 2 headliner, Butterfield was looking to rebound from his first loss in well over two years. His opponent Valavicius hadn't suffered defeat since June of 2011 and was riding his own six-fight winning streak. But all that was about to change.

Using his well-rounded attack, Butterfield was able to negate the Lithuanian's heavy hands and work his way to a unanimous decision victory. The win was a major step for "The Mason" and arguably the biggest moment of his career.

Outside of adding a respectable to name to his hit list, the win also showcased Butterfield to a larger audience in the Chicago market and moved him to headliner status within the up-and-coming Flawless Fighting Championship organization.
