I love "contact" sports. But someone is going to get killed here!

"Russian MMA fighter Ivan Chugov battered his rival Pavel Molchanov in an outlandish and literal "phone booth fight" in Russia this week.
The young duo competed in the second episode of the second season of promotion Punch Box, in which fighters step into a traditional red London phone booth and have a boxing match of sorts in MMA gloves. The idea is clearly taken from the old cliche in combat sports of "fighting in a phone booth", and has a number of competitors as well as a solid following."
