In today's EPL match between Chelsea and Sunderland, Juan Mata of the former felt some cleats drive into his back from the foot of opponent Phil Bardsley.
Bardsley's immediate reaction seemed to indicate it was an accidental half-stomping. The replay seemed to indicate that Bardsley put enough force into it that a post-emptive suspension could result.
Sunderland came within a bad cross of tying the match at two in extra time. Chelsea wins 2-1 and remains unbeaten on the season.
