The Browns opened their season against the Philadelphia Eagles. They got their first points of the 2012 season when Phil Dawson kicked a 43-yard field goal to make the score 3-0 for the only points of the opening quarter. The Eagles responded to tie the game at 3-3 when Alex Henery kicked a 42-yard field goal followed by Michael Vick finding Jeremy Maclin in the end zone on an 18-yard touchdown pass to make the halftime score 10-3. Heading into the third quarter and extending into the 4th, the Browns scored 13 unanswered points starting with Dawson's field goals from 42 (for the only score of the quarter) and 22 yards out shortening the Eagles' lead from four to just a point from 10-6 to 10-9. And then, the Browns retook the lead when D'Qwell Jackson ran for a 13-yard touchdown for a 16-10 game. However, the Eagles were able to complete the comeback as Vick found Clay Harbor on a 4-yard pass making the final score 17-16. The Browns started their season 0-1 for the eighth straight year.
