Keselowski had post-race run-ins with drivers Denny Hamlin and Matt Kenseth on the track and in the garage following the race. Keselowski was fined $50,000 by NASCAR and placed on probation for four weeks.
Following a discussion by Keselowski of how he didn't allow what happened to alter his focus for this week's race, Penske jumped on the chance to defend his driver.
"Number one, these guys are jealous of the job he's done this year. He's won six races. He's made poles. He's been up front. Nobody likes to see a guy win like that. The fact that he has a little edge on him, he's continually delivering, obviously I think makes a difference," he said.
"If everybody understood what happened on the race track last week, when you get your rear fender knocked off on a restart, you get your front fender knocked off on a pass‑by, I want him to get mad. I don't want him to take it.
"So to me coming back, we talked about it Sunday night, I said, 'Let's just go on, do our test during the week, move on here. Brad, I said, Put it in the rear view mirror.'"
