Saturday night’s UFC ON FOX event from the United Center in Chicago, posted a 2.7/5 household overnight rating/share, +42% better than FOX’s Saturday primetime average for the previous four weeks (1.9/4), according to Nielsen Media Research.

FOX Sports Research projects that the network is expected to win the night among Adults 18-49 by a wide margin, and may beat ABC, CBS and NBC combined in the Adults 18-34 demographic when national figures are issued tomorrow.

The three-bout, two-hour event, the first official network broadcast of FOX’s partnership with UFC, is off from the UFC on FOX premiere in November (3.5/6), which was only one hour and featured a highly anticipated heavyweight championship fight. When comparing similar time periods for the two events, FOX posted a 3.1/5 from 9:00-10:15 PM ET, compared to the 3.5/6 that the premiere event recorded from 9:00-10:00 PM.

As anticipation to the night’s main event grew so did the ratings. The night’s first match, Jitsu master Demian Maia taking on unbeaten Chris Weidman did a 2.3/4. The next fight between middleweight contender Chael Sonnen battling British star Michael Bisping grew to a 2.9/5. Fans tuned in to see former light heavyweight champion Rashad Evans take on undefeated former national champion wrestler Phil Davis with that bout posting a 3.4/6. The fight went all five rounds and Evans defeated Davis by unanimous decision.
