Flyweight  Andre Lima remained undefeated and picked up his first octagon win on Saturday during the UFC Vegas 89 preliminary card when his opponent was disqualified.   During the second round of their bout,  Igor Severino bit Lima on the arm while attempting to take him down.  Lima alerted referee Chris Tognoni and showed him the bite mark.  Tognoni halted the fight and disqualified Severino.  The bite marks could clearly be seen on Lima’s arm during his post-fight interview.  Severino received his pink slip from the fight promotion following the brazen rule violation.
