Denver Broncos have moved to 5-0 in the AFC West after Chris Harris's fourth-quarter pick six helped them to beat the Oakland Raiders.

The Raiders missed the chance to take lead in the early stages after Sebastian Janikowski's field goal was blocked by Denver's special teams.

Brandon McManus then successfully converted a 25-yard field goal attempt to give the Broncos a slender lead.

However, Oakland hit back through Derek Carr's pass into the corner of the endzone for Marcel Reece, to edge the hosts in front.

Peyton Manning looked to be driving his team into position for a late second-quarter touchdown, but the future Hall of Fame quarterback was intercepted by veteran safety Charles Woodson for the first time in his career.

Denver started the second half well as Carr fumbled after being sacked, which allowed Von Miller to recover the ball before McManus kicked successive field goals to give the visitors the lead.

Manning then gave up another interception to Woodson, but the Broncos would respond in kind midway through the fourth quarter as Harris intercepted Carr and ran back for 74 yards to increase their lead to 16-7.

Carr tried to lead the Raiders back into the game and, despite a late Janikowski field goal, they ultimately fell short.
