It was supposed to be a day of celebration for Houston.

A continual onslaught of coaching rumors threatened to pry away coach Tom Herman after just one season. The former Ohio State offensive coordinator was one of the most coveted names during┬áthis week’s rush of job openings.

Instead, Herman agreed to remain with the Cougars into 2016.

On top of that, Houston beat Temple, 24-13, to secure a 12-1 record and a trip to either the Peach Bowl or Fiesta Bowl as the lone Group of 5 representative. The win also may have clinched a spot in the final Associated Press Top 25, regardless of what happens in the bowl game.

Thousands of fans rushed the field at TDECU Stadium to celebrate the American Athletic Conference title with Herman, quarterback Greg Ward Jr. and each other.

Instead, the security guards contracted by Houston body-slammed and tackled them to the ground, as several videos showed. One security guard even appeared to punch a fan in the face.

In a statement on its website, CSC said it was looking into what happened.

“Training is provided to CSC employees for responding to such situations,” the company said. “Any actions by CSC personnel that contradict our training, CSC’s other requirements, or the law, are not condoned by CSC and will not be tolerated. We are currently performing an investigation of the events and will take appropriate action based on the outcome of our investigation.”

Here’s a look at some of the video from Houston:
