Two plays later, Brady hit White for a 30-yard touchdown, widening the lead to 21-3. Zach Mettenberger replaced Mariota on the next drive, and the Titans drove to the Patriots 38, but on 4th-and-1, Antonio Andrews stuffed for no gain. The Patriots drove to the Titans 25 and Gostkowski increased the lead to 24-3 on a 43-yard field goal. Amendola returned the ensuing punt 22 yards to the Patriots 45. The Patriots drove to the Titans 30, but Gostkowski missed the 48-yard field goal wide right, keeping the score 24-3 at halftime. After the Patriots punted, aid by an 18-yard punt return by Harry Douglas, the Titans drove 59 yards in 7 plays, with Mettenberger finding Delanie Walker for a 7-yard touchdown, trimming the deficit to 24-10. The Patriots responded by driving to the Titans 20, and Gostkowski was good from 38 yards away. Three possessions later, the Titans reached the Patriots 36, but Mettenberger was intercepted by Butler at the 2.
