How did Cassel get a concussion?

[Mr. Arrowhead]

Im still confused how Cassel got a concussion, first off nobody even touched his head on the hit, and then he tried to get up and he holds his shoulder

[Mr. Arrowhead]

did he get hit before this play? I guess its possible that he gets a mild concussion before this play, and that little hit just finished him off

looks like a check to me

he looks around to all the offensive players and yells omaha to both sides like he's checking off.

i dunno ... it LOOKS like a check

It looks like a check because he's changing the snap count.

"Omaha" is similar to "on 3".
