Several Gophers leapt to senior safety Cedric Thompson's defense Saturday, after he got leveled by a personal foul from Purdue receiver Danny Anthrop.
Defensive back Derrick Wells ran off the bench and confronted Anthrop, which could have led to discipline from the Big Ten office.
And middle linebacker Damien Wilson received a 15-yard unsportsmanlike conduct penalty for pushing Anthrop to the ground.
Kill said he used the play as a teaching moment for his players.
"Football is a game of emotion, and sometimes things happen," Kill said. "But our jobs as coaches, we need to do everything we can to prevent it. Because the worst thing we can do is have a great player sitting on the sideline."
Kill sounded confident that Wells would not draw a suspension from the Big Ten.
"No, he's substituting in," Kill said. "I've talked to the people in charge. And that's part of that teaching moment. And that's one young man we certainly talked to."
Line gets healthier
Kill thought the offensive line had its best game of the season against Purdue, and now it's getting healthier.
