There's no way they would have let him fight with a concussion. If he'd had a concussion the fight would one hundred percent not have happened. He would have developed an excuse injury and pulled out. He got properly buzzed in the third round and gradually fell apart. A little bit David Price like and worryingly when he turned his back and really didn't seem eager to continue a little bit Victor Ortiz like. I can see the same thing happening in the rematch. He's made a lot of money and doesn't like getting beaten up.
