The Oakland Raiders hold a narrow three-point lead over the Buffalo Bills at the break in their NFL clash with the score at 13-10.

The Bills got on the scoreboard on their first possession of the game as Kyle Orton fired the ball deep downfield to the endzone, where Sammy Watkins made an impressive grab off Charles Woodson to secure the 42-yard touchdown.

Woodson made a crucial interception soon after to quell the Bills' next drive, but Derek Carr could not take advantage on offense as he failed to move his side into the red zone.

At the start of the second quarter, the Raiders managed to get back on level terms as Carr fired deep to Kenbrell Thompkins, which set up a three-yard strike to James Jones at the back of the endzone.

Oakland continued their strong second quarter when Carr moved them into field-goal range again and Sebastian Janikowski fired over from 45 yards, while the kicker added another three points from 36 yards with two minutes remaining.

There was still time late in the half for the Bills to move into range for a field goal from Dan Carpenter, which he made with ease from 54 yards.
