Pacman's right shoulder injury did some damage but it was his team to be blamed by convincing the star to go on with the fight schedule despite Roach insisting it.
Without his permission it would not be possible, they did that for the money, they don't want to disappoint the fans and it's the biggest payday of Pacman so they are taking advantage on it despite knowing the fact that Manny can't give his 100% in the fight.
