Hate to see this; hopefully it is not serious.

Damn!

That sucks

He was looking good up until that point. It looked more like a hamstring on TV but a knee is worse. Poor guy has had some real bad injury luck.

Today from Mike Vrabel -
"-Running back Darrynton Evans is day-to-day after suffering a knee injury on Friday, and he'll be evaluated.

"I would just say day-to-day and we'll see where he is when we get down to Tampa," Vrabel said."

Sounds like it was just an abundance of caution with it being the first pre season game.
