I broke my arm playing pickup football and did not notice it. When adrenalin was out of my system I discovered I broke both of my bones in my forearm clear through and my arm made a Z shape. I was in cast for next few weeks. Broke cast over head of someone who thought it was funny that he could pin me with good arm in locker. While he was stunned I picked him up with one good arm and held him by his neck hanging over railing in Amsdell middle school (now called Frontier Middle School), I was suspended for a week and him for a month. No one ever picked on me again in school.
It is a amazing what you can do when adrenalin and other hormones are high, The opposite can happen if your nerve is hit at wrong angle.
Depends if Bills can get a doctor with reference from Mijami's doctor to clear him.
