It’s sad that that’s the state of the world we live in. It’s a football game. Let’s not make it more than that. We don’t want anybody to get hurt. We don’t coach that kind of football.”

Norvell commented on the nature of Blackburn's hit on Hunter.

“I reviewed the play. It’s a play that happens sometimes," he said. 'When you throw a deep ball and have a guy playing middle safety, he’s got to react on the boundary and he’s going full speed. It was a bang-bang type of a play.

"The officials looked at it and we looked at it. It’s certainly not something that we teach or coach. It happens in football sometimes. Seems to have been a lot of attention about that play, but it’s a play that happens."
