Challenge Cup: Wigan Warriors to face Dewsbury Rams
Holders Wigan Warriors face a trip to Championship side Dewsbury in the fourth round of the Challenge Cup.
The Warriors beat Hull FC 16-0 in last season's showpiece at Wembley.
Last season's losing finalists face a home tie against Salford Red Devils in one of five all-Super League ties.
In other ties, St Helens travel to Huddersfield, Wakefield host Leeds, Hull KR face Warrington and Catalan Dragons play host to fellow Super League strugglers London Broncos.
Castleford face a trip to West Yorkshire rivals Batley Bulldogs and Widnes will travel to Halifax in the only ties, apart from Wigan v Dewsbury, between teams from the top and second tier, while financially-troubled Bradford Bulls host Championship One opposition in the form of Oldham.
There are all-Championship ties with Featherstone facing North Wales Crusaders and Keighley hosting Barrow while Workington, Sheffield and Swinton will all be hoping to avoid upsets when they play Hunslet, London Skolars and York City Knights respectively.
All 16 fourth-round ties will be played between 4-6 April.
