Buffalo Bills defensive end Mario Williams criticized the NFL's replacement referees for missing many illegal hands to the face penalties during Sunday's 48-28 loss to the New York Jets.
The free-agent acquisition felt Jets right tackle Austin Howard should've been flagged numerous times in the game.
"Pass blocking doesn't consist of illegal hands to the face just about every play, which, when somebody tells you that, and you're five yards away from it, and you walk away like you don't see him telling you you're getting punched in the face every time, then that dictates somebody like myself having to take care of that on my own," Williams told reporters.
"There's definitely, with the situation that we're in with the refs like that, and then you don't listen or you don't call it one time out of 20 that were out there. That's really disheartening from that point."
Williams was held without a sack on Sunday.
"I had some things going on, so I stayed on the left side, but it's just one of those things where you tell somebody from the beginning of the game -- and it happens, one time that's on me," Williams said. "But when it's multiple times and I tell you and honestly you act like you don't hear me throughout the whole game, I think that's a big problem."
