No broken arms?

At the beginning of the season they show short clips of the rest of the reason. One of them is of the main NYer in the first episode hurting his arm. I think we hear a crack during one of his matches. He visits a doctor who tells him he has injured it and shouldn't continue, but we don't know if he will or not.

The pullers on the show are all pros, so you won't see a broken arm. Maybe some other injury, but very unlikely you'll see a pro break an arm.

Most of the arm breaks you see in armwrestling are beginners who have bad technique and/or unconditioned arms.
