The Philadelphia Eagles opened up the season by traveling to Cleveland to square off against the Browns.  A 43-yard field goal by veteran Browns kicker Phil Dawson gave Cleveland a 3-0 lead some six minutes into the first quarter.  The Eagles would respond with a field goal of their own, though, as Alex Henery sent the ball through the uprights from 42-yards out just seconds into the second period.  With the score tied at 3-3 and just seventeen seconds before the half, an 18-yard pass from Eagles' quarterback Michael Vick to wideout Jeremy Maclin extended the Eagles lead by seven.  At the half, the score was 10-3, the Eagles leading the Browns by a seven-point margin.  Browns kicker Phil Dawson successfully converted another field goal from 42-yards away with just under five minutes left in the third quarter, trimming the score to 10-6.  Shortly afterwards, Dawson made the score 10-9 with a 22-yard field goal, his third of the day, and narrowing the Eagles' lead to one point with about fourteen minutes left in the game.  The underdog Browns continued the scoring streak, taking the lead on an errant Michael Vick throw and 27-yard interception return touchdown by D'Qwell Jackson approximately thirty seconds later.  With the score at 16-10 and an upset in the works, Michael Vick calmly drove the Eagles down the field and threw a strike to Clay Harbor from 4-yards out to return the lead to Philadelphia, 17-16.  The Browns were unable to reciprocate and the Philadelphia Eagles narrowly claimed the week one victory.  With the nail-biting win, the Eagles began their season 1-0..
