Ten fighters who competed at UFC Vegas 48, including main event winner Jamahal Hill, could face six months away from the cage.
Hill continued his impressive run at light heavyweight by knocking out Johnny Walker in the first round, banking his second consecutive $50,000 performance bonus.
But despite only fighting for less than three minutes, Hill must have an x-ray on his left elbow and right forearm and an MRI on his left knee before being cleared to fight again.
Hill's arm was visibly swollen after the fight as UFC commentator Paul Felder pointed out in his post-fight interview, but Hill insisted it wasn't sore.
Since being signed to the promotion after impressing on the Contender Series, Hill has won four of his six UFC appearances.
'Sweet Dreams' has broken into the top ten at 205lb with his recent win and called out former title challenger Volkan Oezdemir for his next fight.
Abdul Razak Alhassan, who lost a split decision to Joaquin Buckley on the main card last weekend, revealed he broke his rib in the loss.
As well as an x-ray of his left rib, Alhassan must have his left foot, right wrist/hand and right hip observed before being allowed to return to the cage.
Gabriel Benitez was knocked out by David Onama, who became the first-ever Ugandan fighter to win in the UFC.
Benitez has been handed a six-month suspension, meaning he will be unable to fight until August unless he can get a knee injury cleared by a doctor.
Jessica-Rose Clark will need to undergo an MRI on her right elbow after she was submitted by accomplished Judoka Stephanie Eggar in the first round.
