Wigan Warriors have seen their hopes of finishing at the top of the Super League table suffer a blow with a shock defeat at Bradford Bulls.

Tries from Danny Williams, Joe Arundel and Matty Blythe saw the lowly Bulls earn a 16-8 victory, while the Warriors got on the scoreboard with two scores from Dom Manfredi.

Shaun Wane's side have now lost three of their last six matches in the league.

Meanwhile, Huddersfield Giants have tightened their grip on a place in the playoffs thanks to a convincing 38-16 victory at home to Catalans Dragons.

Three tries inside the opening 20 minutes put the Giants in a dominant position before four scores after the break allowed them to register a second consecutive triumph. Jermaine McGillvary and Joe Wardle ended the match with two scores apiece.

Elsewhere, Wakefield Trinity Wildcats caused a second upset of the day with a 40-26 win away to Warrington Wolves.

Chris Riley was the star of the show for the Wildcats as his hat-trick pushed them towards only their ninth victory of the campaign.
