Giants move three points clear
Huddersfield edged closer to securing their first ever League Leaders' Shield with a 26-12 victory over London Broncos.
Having seen rivals Warrington lose 16-6 at home to Widnes on Thursday, the Giants knew victory at bottom side Broncos would open up a three-point lead at the top of the table.
Scores from Aaron Murphy, Ukuma Ta'ai and Eorl Crabtree racked up an 18-0 lead midway through the second half, with scrum-half Danny Brough adding six points with the boot.
But the hosts battled back in their final home game of the season with efforts from James Woodburn-Hall and Alex Hurst making it a nervy finish for Huddersfield.
Brough was subsequently helped from the field clutching his shoulder, an ominous sign with the play-offs looming, before a late penalty from Scott Grix and a fourth try from Dale Ferguson eased the jitters for the Giants.
Catalan Dragons secured their place in the play-offs with a 22-8 win over Wigan.
The Perpignan side knew a win would put them eight points clear of Bradford with the Bulls having just three games to play and, with their mission complete, it is now a three-way fight for the last play-off spot between the West Yorkshire club and the two Hull clubs.
None of that will be of concern to either of these sides, though, with Wigan heading to the capital to meet Hull in the Challenge Cup final next weekend, knowing their chances of finishing top of the table are now over.
Catalan went ahead after 17 minutes as Freddie Vaccari crashed over for a score which was approved by the video referee.
Thomas Bosc converted but the home side started to invite pressure with a series of errors which allowed Wigan to set up camp in their half.
After three sets did not yield a try, Scott Taylor took the direct route on the stroke of the half-time hooter and smashed his way over, with Pat Richards converting.
A cagey opening to the second half saw the two sides trade penalties through Bosc and Richards, but Catalan eventually pulled clear.
Bosc split the posts with two more penalties to open a four-point gap and then 39-year-old Steve Menzies pushed his way over.
Wigan were unable to respond and Eloi Pelissier put them further out of sight with a try converted by Bosc.
