Texas Tech fans -- even before the final second -- were pouring out of the stands and onto the field to celebrate the upset of then-No. 1 Texas.

The field in Lubbock had to be cleared twice after the go-ahead touchdown by the Red Raiders.

Tech was given two unsportsmanlike conduct penalties.

The Red Raiders then kicked off from their own 7-yard line before the game ended Saturday night and the fans swarmed the field again.

Texas coach Mack Brown says the Big 12 and the NCAA should do something for the security and safety of those kids and coaches after games like that.

Brown says -- it's really dangerous.

Brown applauded Texas Tech and Lubbock for creating a "great atmosphere" to make it a special and exciting game.

But he worries about opposing teams trying to get off the field through chaotic celebrations.
