However, Phillips also knows it's not the worst thing to have a football team show its aggressiveness that way, especially when he brought in new line coaches Mike Summers and David Turner to make the Cats a tougher, more physical team.
"They did mix it up. Nothing wrong with that. This is a violent sport," said Phillips. "They just got caught up in it. We just have to make sure they leave it on the field.
"We practiced with a lot of energy — but we need a lot of energy tomorrow (for UK's first full scrimmage)."
Phillips said one of his former UK coaches, Jake Hallum, who was at Friday's practice, always told him that the most important thing was "to get ready for the next play" and that's what he wanted to see how players responded following the altercation.
Saturday he wants to see how a number of players will do in what he called "an important scrimmage" for his team.
"We are going to see where a lot of people are at," Phillips said. "There is an important quarterback battle. Those guys need a good scrimmage."
Quarterbacks Mike Hartline, Morgan Newton and Ryan Mossakowski are sharing practice reps even though Hartline and Newton appeared to have more chances than Mossakowski again Friday. Phillips said he'll do his best to make sure they have equal work in Saturday's scrimmage.
"They all threw well. They threw down the field better," Phillips said. "I want to see how they run the offense. I want to see the tempo in and out of the huddle."
He also liked that UK had numerous receivers make plays.
"That helps the quarterback's confidence, too," the UK coach said. "Andre (Woodson) threw the ball up there because he knew guys would make plays. The quarterback has to understand what is open and where to throw the ball, but all three are getting better at that."
