At :50 clearly Rampage is seen hovering over the fence in Kimbo's corner.
But, take into consideration this-
In seasons prior, when one team blows out the other in the first round of fights, when they have "teammate vs. teammate" fights in the second or third rounds they have been known to send guys over to be cornered by the other coach during the fight.
I HEAVILY doubt this is the case,
Kimbo and Quinton seem like a perfect match, imo.
