In their first Thanksgiving Day game, the Panthers debuted their all-Panther blue Nike "Color Rush" uniforms while the Cowboys debuted all white. Carolina intercepted three passes from Dallas QB Tony Romo, one less than a minute into the game by DB Kurt Coleman, who returned it for a touchdown. Kuechly had his first pick-six of his career minutes later and on the Cowboys next offensive series intercepted Romo yet again. Romo was later injured on a sack and would leave the game. He ended up missing the rest of 2015 (and most of 2016). Romo was replaced by Matt Cassel. With a blowout win the Panthers improved to 11-0. Due to the Patriots' overtime loss to the Broncos on November 29 during Sunday Night Football, the Panthers became the last undefeated team in the NFL and would remain so for the following month.. How many quarters did Romo play in?
