Morris left the game in the second quarter after reinjuring his ankle, which he hurt last week against Savannah State.
According to The Palm Beach Post, Morris said, "South Florida's a dirty team. When you're down and tackled and everyone's on top, they're going to try to go for your ankles. We were up three, four touchdowns. Ain't no point for me to mess with these guys who are going to play dirty.
"It is what it is. I wanted to score 70 points on them. They disrespected us, so I had no respect for them. At that point, I felt like we should just keep pushing it, keep killing them."
Morris had thrown for 222 yards and two touchdowns to put Miami ahead 21-7 when he left the game. For the second straight week, Ryan Williams replaced Morris. Williams finished with 153 yards on 8-of-14 passing, with a touchdown and an interception.
