Answer based on context:

Trying to snap a three-game losing streak, the Raiders went home for a Week 6 interconference duel with the Philadelphia Eagles.  In the first quarter, Philadelphia delivered the opening hit as kicker David Akers made a 45-yard field goal.  The Raiders would answer with quarterback JaMarcus Russell's 86-yard touchdown pass to tight end Zach Miller.  In the second quarter, both teams swapped field goals as Oakland's Sebastian Janikowski got a 29-yard field goal while Akers gave the Eagles a 43-yard field goal.  After a scoreless third quarter, the Raiders turned to Janikowski again in the fourth quarter as he booted a 46-yard field goal.  Philadelphia tried to make a comeback, but Oakland would only allow a 45-yard field goal from Akers.
