The Carolina defense returned two of Romo's three interceptions for touchdowns before the Dallas quarterback re-injured the collarbone that sidelined him for seven games and the Panthers pushed their NFL-best winning streak to 15 games in the regular season with a 33-14 victory in their Thanksgiving debut Thursday. Newton had his team's only offensive touchdown on a 4-yard run, and Carolina became the 16th team to start a season 11-0. The defending NFC East champions were already headed to an eighth loss in nine games a week after Romo ended the skid in his return at Miami. Luke Kuechly intercepted two straight passes by Romo late in the second quarter, returning the first 32 yards for a touchdown. Coach Jason Garrett said Romo would play if he was cleared even with the Cowboys unlikely to have a realistic shot to defend their division title. The league's top tackler since joining the NFL in 2012, Kuechly dropped into coverage and easily stepped in front of a pass intended for Terrance Williams before churning up the left sideline and pushing Romo away as he crossed the goal line. The linebacker looked a little winded on the return, eventually settling for a 17-yarder that led to the third of Graham Gano's four field goals to put the Panthers up 23-3 at halftime. Dallas defensive end Greg Hardy had a quiet game against his former team, finishing without any tackles and missing most of the second half with an injury Garrett wouldn't specify.
