Cowboys trip over Pats

Brace Hemmelgarn-USA TODAY Sports

The Patriots defeated the Cowboys 13-9 in New England and there was controversy over a tripping penalty on Travis Frederick. The penalty negated a first-down pass to Ezekiel Elliott on third-and-1 in the final two minutes of the game and resulted in the Cowboys facing an eventual fourth-and-11. It was one of two tripping penalties on Cowboys offensive linemen, with another being called on Tyron Smith.
