I take most injury claims with a grain of salt when it comes to boxers, especially when discussed after the fight.
Personally I am going to take Roy's word for it. He is already an ATG and has no need to lie. I really enjoyed the fight.
Tito has only been KO'd once in his career and that was in the final round of a fight he knew he was losing....he had to go all out to try and KO Hopkins and in return hit the canvas himself and lost......that being said, Tito has alot of heart and knocking him out would not be easy for any future opponent. I take nothing away from Roy for trying...but again, it is no easy task to KO Tito.
Look at the bloody video. It`s obvious his bicep had a bump/injury on it where he pointed at. Jesus, some people like to mouth off without even taking that little bit of energy to actually check things out.
If he tore a tendon in his left bicep in training camp then he should retire cause his ass is getting old
