Seattle Seahawks wide receiver Golden Tate has been slapped with a big fine from the NFL league offices for his hit on Dallas Cowboys linebacker Sean Lee.

Tate blindsided Lee in the third quarter of Sundays 27-7 loss for Dallas.

The NFL won’t announce the amount until later in the week, but a first offense in this category carries a $21,000 fine under the collective bargaining agreement.

Tate was not flagged for a penalty on the play even though it was a hit on a defenseless player. In fact, the Cowboys were assessed a 15-yard penalty at the end of Russell Wilson’s scramble when Bruce Carter was called for pushing the quarterback out of bounds.
