The sixth-round of the Challenge Cup welcomes the remaining Super League sides that played in the Super 8s last season including St Helens, Wigan Warriors, Castleford Tigers, Warrington Wolves, Huddersfield Giants, Hull FC, Wakefield Trinity and Catalan Dragons.
2018 winners Catalans Dragons will be confident of progressing to the quarter-finals as they begin their defence of the title at home against Doncaster, the lowest side left in the competition. However, the League 1 side proved they are no pushovers in the fifth-round as they defeated Batley Bulldogs of the Championship.
Bradford Bulls will host Leeds Rhinos in a Yorkshire derby - the first time the sides have met competitively since the Bulls dropped out of Super League in 2014 and there is an all-Super League tie as Salford face Hull Kingston Rovers.
Warrington Wolves will hope for a repeat of their recent victory over Wigan Warriors in the Super League as they welcome the Warriors on Sunday, with Huddersfield Giants hosting St Helens in the final fixture of the weekend.
The BBC will show games from each round of the Rugby League Challenge Cup live on the BBC Sport website and app and on TV in 2019.

The current holders of the Challenge Cup are Catalan Dragons who defeated Warrington Wolves 20–14 to become the first non-British team to win the competition in its 117-year history.
Wigan Warriors are the most successful club in the history of the competition, winning the cup a record 19 times.
