Peyton Manning threw for 338 yards as the Denver Broncos snapped a two-game losing streak with a 37-6 rout of the Oakland Raiders at Sports Authority Field. Manning completed 30 of his 38 pass attempts and connected with Eric Decker, Joel Dreessen and Lance Ball on touchdown passes. Willis McGahee added 112 rushing yards and a touchdown. All told, the Broncos outgained the Raiders 507 to 237 on the day and were so dominant offensively that they didn’t punt once all afternoon. But it wasn’t all sunshine for the Broncos, as they lost starting center JD Walton, likely for the season. Walton broke his ankle in the second quarter. The Broncos move their record back to .500 at 2-2. They play four out of their next five games on the road, starting next Sunday in Foxboro against the New England Patriots.
