The co-main event at UFC 127 featured Michael Bisping and Jorge
Rivera in what had developed into a grudge match in the weeks
leading up to their middleweight contest.  Rivera had been
posting videos on YouTube that took pointed shots at Bisping. By
the time the pre-fight press conference rolled around, it was
clear that Bisping was annoyed with Rivera.  During the question
and answer session, Bisping took every chance he could to direct
a biting comment at Rivera.  Rivera, for the most part, sat
silent on the dais; his baseball cap pulled low.  When the
fighters faced off for the staredown, Bisping unleashed a string
of insults at Rivera.  The bad blood spilled over into the
weigh-in when the two fighters had to be physically separated by
UFC president, Dana White.  In a way, the fight was anti-
climatic due to the way it ended. Bisping landed an illegal knee
to the head of Rivera during the first round. The knee caused
Rivera to spend several minutes recovering while he was attended
to by the cageside doctor
