In the 4th quarter of the week 11 game between the Minnesota Vikings and Arizona Cardinals, defensive tackle Tom Johnson got a hit on quarterback Carson Palmer which drew a penalty for roughing the passer.
At the time, Johnson seemed to be disappointed with the call on the field, but it appears as though the NFL feels the hit deserved a little more of a penalty, and fined the defensive lineman $18,231 according to the Pioneer Press.
Of course, all fines can be appealed. Since Johnson feels so passionately about the play, it is possible he will go that route as he feels the play was clean.
