Coming off their last-second home win over the Cardinals, the Ravens flew to Cleveland Browns Stadium for an AFC North duel with the Cleveland Browns.  The match-up would be notable with former Ravens RB Jamal Lewis now playing for Cleveland.  In the first quarter, Baltimore trailed early as the Browns took their opening drive and ended it with QB Derek Anderson (another former Raven) completing a 2-yard TD pass to WR Joe Jurevicius.  Also, immediately after QB Steve McNair got intercepted, Cleveland cashed in with Anderson completing a 78-yard TD pass to WR Braylon Edwards.  In the second quarter, Baltimore managed to get on the board with kicker Matt Stover getting a 21-yard field goal.  However, the Browns continued their offensive surge with kicker Phil Dawson getting a 41-yard field goal, along with Lewis getting a 1-yard TD run.  Even though instant replay showed that the ball was just shy of breaking the plane of the goal line, the Ravens' coaching staff was unable to challenge the play in time.  They would end the half with Stover kicking a 29-yard field goal. In the third quarter, Cleveland continued its surgence with Dawson kicking a 20-yard field goal for the only score of the period.  In the fourth quarter, Baltimore tried to come back, but the only thing from their comeback was McNair's 4-yard TD pass to TE Quinn Sypniewski.  With the surprising loss, the Ravens fell to 2-2, despite outgaining the Browns 418-303 in total offense.  On the positive note, RB Willis McGahee got his first 100-yard game as a Raven, as he ran 14 times for 104 yards.
