The Oakland Raiders and the Baltimore Ravens have both enjoyed success on offense in the first half as their NFL clash is tied up at 20-20 at the break.

The Raiders had the perfect start to the game when Derek Carr sent the ball long to rookie wide receiver Amari Cooper on a go route down the sideline and he made the grab for the 68-yard touchdown.

A fumble from Kamar Aiken allowed the Raiders to extend their lead as Carr moved his side into field-goal range and Sebastian Janikowski nailed his kick from 23 yards.

Ravens quarterback Joe Flacco moved his side into the redzone, and although they failed to score a touchdown, Justin Tucker fired a 22-yard kick through the posts.

The AFC North side levelled the scores at the end of the first quarter when Flacco delivered the ball to his tight end Crockett Gillmore for a 26-yard score. However, the Raiders hit back as they notched another touchdown early in the second quarter, Latavius Murray finding the endzone on the goalline.

Gillmore scored his second touchdown of the game when Flacco fired him in the ball five yards from the line and he bustled through two tackles to get into the endzone, but Janikowski restored the Raiders' lead with another field goal before the break.

There was still time for Tucker to kick another field goal before the half and he nailed his effort to level the scores.
