Context: Trying to continue their two-game winning streak and keep their playoff hopes alive, the Eagles hosted the Cleveland Browns on Monday Night Football.  The Eagles scored a touchdown on their opening drive - a 14-yard pass from Donovan McNabb to Kevin Curtis.  After trading field goals later in the first quarter, the Eagles took a 17-3 lead when Asante Samuel returned an interception 50 yards for a touchdown.  On the final play of the half, McNabb was intercepted on a fade pass by Brandon McDonald, who returned the ball all the way to inside the Eagle 5-yard line before being forced out of bounds.  David Akers converted a 34-yard field goal in the third quarter to make it 20-3 Eagles.  Following another Akers field goal, McNabb found Greg Lewis on a 10-yard touchdown pass, increasing the lead to 30-10.  Cleveland's sole touchdown came on an interception return by Brandon McDonald off of Eagle second-string quarterback Kevin Kolb.  With the win, the Eagle's winning streak increased to three games, and hopes of a playoff berth continued. Their record went to 8-5-1.
