Johnny Walker fucked around and found out.
He was clowning the doctor when he asked "What country are you in? What round is it?"
Then once the fight got waived off he immediately sprung to life and showed that he wanted to still bang.
Dana was heard in the octagon saying to him "calm down, we'll turn this thing around quickly, the doctor made a mistake."
He's got an interesting situation on his hands: Either Walker WAS concussed, and therefore he is excused of pushing the ref, but as a result the fight won't be turned around quickly due to medical suspension; OR, Walker wasn't actually concussed, and IS eligible to fight, but will be served a suspension due to putting his hands on the ref, also resulting in the fight not being able to be turned around quickly.
