Champions Leeds visit the favourites to take their crown this season, St Helens, on Friday night.
The Rhinos bounced back from their loss at Widnes by turning over Hull last weekend, and travel to a Saints side who have won five out of five in Super League so far in 2018.
Jon Wilkin returns from concussion for St Helens in place of Alex Walmsley, ruled out with a neck injury suffered in the win at Warrington last week.
Leeds have also lost a front-rower – prop Mitch Garbutt sidelined with a knee injury, which means Cameron Smith comes in to the 19-man squad.
TOM BRISCOE needs one appearance to reach 100 for Leeds. Briscoe scored a hat-trick of tries on his Rhinos debut – a 34-6 win at Hull KR on 16 February, 2014.
TOMMY MAKINSON needs two tries to reach a century of touchdowns for St Helens. Makinson has scored 98 tries in 172 games for the Saints since 2011.
JAMES ROBY needs one try to reach a century of touchdowns for St Helens. Roby has scored 99 tries in 404 games for the Saints since 2004.
