"Recovered" is the right word. Petrescu's eyes briefly rolled around his head as he took a step back to catch his composure. Frith, however, was judged to be unable to continue from the concussive shot, leading the referee to call an end to the fight.

"When the referee stepped in, I was a little bit surprised," Petrescu continued, "but when you're fighting you don't know what's going on all the time. Obviously there's some controversy behind it. We can do it again. He's a very durable guy I have to give him credit; he's a very good fighter."
