I wonder why people blame doc? Nate should have protected himself better. The doc has done the right thing - saved the health of the fighter.
It might not be the best stoppage but the doctor is there to take care of the fighter and his health and not to satisfy the audience and i will watch the rematch but Jorge Masvidal is on a good momentum and i would like to see him fight for the belt before going back to the rematch and Nate Diaz have the option to carry on with the Conor trilogy as Conor expressed his wishes to return.
Yes, I agree with what you said that the doctor is there to take care of the fighter and not to satisfy the audience. That's the doctor's job to make sure that the fighter will stay safe ( able to fight with his/her circumstance) also the additional info is that if the doctor let the fighter to fight even to her/his condition the doctor will be blamed to what will happen after he/she got re-examine. But some fans will be surely angry because one of his interview he said this " The doctor played me, he asked me if Im good, I said cool. He goes back to the other guy and says the fights off.Im like, What the f***.
