Uppercut did cause it and honestly Judah would have lost either way. He was breathing from his mouth due to his nose being broken early and was gonna end up running out of gas by the 10th on.
Judah is simply not the elite fighter many thought he can become. His hand speed simply can't overcome his other definciences. Too bad cause now no intriguing fights remain at welterweight. Boxing has officially lost all its luster.
