It was an expensive win for three Cowboys players last week, according to NFL Media.
Cowboys cornerback Trevon Diggs, who had a pick-six late in the fourth quarter, was fined $7,981 for unnecessary roughness for hitting a Patriots player in the facemask after a play.
Cowboys offensive guard Connor Williams was fined $16,394 for an unsportsmanlike conduct penalty late in regulation. The Cowboys gained 24 yards on third-and-25 after the penalty to set up the game-tying field goal.
Cowboys receiver CeeDee Lamb waved goodbye to Patriots cornerback Jalen Mills following his walk-off touchdown catch, costing him $10,300 for unsportsmanlike conduct. Lamb was not penalized since it was the final play.
