^ Messed up bad. Gustafsson was bombarded by Jones in the 4th after that spinning back elbow landed but he was never knocked down and that was only 30 seconds of Jones punishing him. Gustafsson punished Jones to the body and the head for the entire 5 rounds, including the 5th and final. All of those head strikes and shots to the body will add up and that would explain why Jon was having tremors at the hospital, vomiting and bleeding out of his eyes, nose and mouth (source: Brendan Schaub who was next to him in the hospital - The Fighter & the Kid podcast). Jones landed the most significant strikes of the fight in that 4th round but overall he was taking a constant beating and ended up accumulating lots of visible damage as a result. The fight was going to be stopped going into the 5th due to his cut over his right eye but Jones, his corner & the ref, Big John, begged the doctor to let him continue.
Jones clearly got clobbered more, there's no debating it. Jones landed the harder shots though (namely at the tail end of the 4th round). Gus was landing combinations on him and single shots almost at will. Dana, his boss, even said that Jones basically needed that much time to recover because [the accumulated damage] it was comparable to being in a car wreck. Gus was back training in 2 weeks, Jones 2 months.
