context: Still searching for their first win, the Bengals went home for a Week 4 AFC North duel with the Cleveland Browns in Round 1 of 2008's Battle of Ohio.  With QB Carson Palmer out with a sore right elbow, back-up QB Ryan Fitzpatrick was named the starter. In the first quarter, Cincinnati trailed early as Browns kicker Phil Dawson got a 25-yard field goal.  In the second quarter, the Bengals took the lead with kicker Shayne Graham getting a 42-yard and a 45-yard field goal.  After a scoreless third quarter, Cleveland regained the lead in the fourth quarter with QB Derek Anderson completing a 4-yard TD pass to WR Braylon Edwards, along with RB Jamal Lewis getting a 1-yard TD run.  Cincinnati would respond with Fitzpatrick completing a 4-yard TD pass to WR Chad Ocho Cinco, yet the Browns pulled away with Dawson nailing a 29-yard field goal. With yet another loss, the Bengals fell to 0-4 while the Browns improved to 1-3.
