Royal also caught two passes for 25 yards and a score for the Broncos (3-5), who have won two of three. Willis McGahee, who missed last week's 45-10 loss to the Lions with a broken hand, carried the ball 20 times for 163 yards and two touchdowns.
Tim Tebow completed 10-of-21 passes for 124 yards and two touchdowns. The Florida product also carried the ball 12 times for 117 yards.
Carson Palmer, making his first start as a Raider, connected on 19-of-35 passes for 332 yards, three touchdowns and three interceptions for Oakland (4-4), which has lost two in a row since a two-game winning streak.
