Carolina answered with a touchdown by Fozzy Whitaker which tied the game again. The Patriots later scored with another Stephen Gostkowski field goal. Devin Funchess caught a ten-yard pass from Newton to give the Panthers a 17-13 lead. With four seconds remaining in the half Gostkowski kicked a 58-yard field goal, making the halftime score 17-16.
