After suffering a disappointing loss to the previously winless Jaguars the week before, the Browns faced yet another winless opponent in the Oakland Raiders.  Both teams struggled for much of the game, kicking a combined five field goals as the Browns held a 9-6 second half lead.  At the end of the third quarter the Browns finally got the break they needed when S Joe Haden recovered a Darren McFadden fumble deep in Cleveland territory and returned it 34 yards.  Four plays later, QB Brian Hoyer found WR Andrew Hawkins for a four-yard touchdown pass and a 16-6 lead.  The Raiders would never recover and the Browns, despite giving up the Raiders' lone touchdown pass from Derek Carr to Andre Holmes with 7 seconds left, won the game 23-13.
