Amazing to hear what some fighters train through

After breaking his thumb during sparring, a trip [to hospital] was unavoidable. It was then Gamburyan learned he also had a fractured elbow.
...
Although he knew immediately when he broke his thumb, Gamburyan was unaware of the extent of the damage to his elbow. He trained through the injury for three months.

"I didn't want to go for an MRI," he said. "I didn't want to know the results. Either way, I really wanted to fight."
