18. Why You Trippin', Dog?
Athlete: Brian Griese
Injury: Sprained his ankle after tripping over his dog on a flight of stairs. Missed a game.
They say that dog is man's best friend. But Brian Griese's dog should be known as man's worst enemy after tripping Griese and causing him to fall down a flight of stairs. Either that, or Griese is just as much of a klutz in his personal life as he is on the field. We'll go with the latter.
