A scary moment occurred during the Texans-Dolphins game Sunday when Miami quarterback Trent Green knocked himself out trying to block Houston defensive tackle Travis Johnson. Green, who missed significant time last year due to a serious concussion, lay motionless on the field for several seconds and eventually was taken off the field on a gurney.

Johnson, irate that Green tried to take his knees out, stood over the motionless QB and began taunting him after the play had ended. Johnson was still fuming after the game and showed little concern over Green’s health.

This is what Keith Olbermann of NBC had to say about Johnson’s reaction during halftime of the Bears-Packers game Sunday night:

Well said, Keith. Johnson has close to 100 pounds on Green – how else is Green supposed to block him? Not to mention, by league rules, it was a legal hit.
