Where to watch: Sky Sports 1
Probable Hibernian team (4-4-2): Virtanen; Gray, McGregor, Hanlon, Stevenson; Fyvie, McGinn, Henderson, Boyle; Cummings, Stokes. Subs from: Logan, Thomson, Bartley, Handling, Shaw, Gunnarsson, Dagnall, Donaldson.
Unavailable: El Alagui, Carmichael, Fontaine, McGeouch (all injured); Keatings, Oxley (both suspended).
Team news: Captain David Gray was taken off just after half time in the 2-2 draw with Falkirk. Norwegian stopper Niklas Gunnarsson could deputise if Gray doesn’t make it, with youngster Callum Donaldson in line for a seat on the bench. Hibs will definitely be without Dylan McGeouch, who is nursing a troublesome groin complaint but Liam Henderson could return to the starting XI after starting on the bench midweek.
Probable Dundee United team (4-4-1-1): Kawashima; Knoyle, Morris, Dillon, Dixon; Paton, Demel, Rankin, Dow; Murray; Mckay. Subs from: Szromnik, Erskine, Spittal, Fraser, Donaldson, Anier, Ofere, Muirhead.
Unavailable: Durnan (suspended).
Team news: Mixu Paatelainen has nearly a full squad at his disposal, but the Finn will be making most changes in defence, with Mark Durnan suspended and Gavin Gunning having left the club this week. Sean Dillon and could come in for the suspended Durnan, while Coll Donaldson is another option. Henri Anier, who spent time on loan at Hibs, scored a brace in the last round for United, but has struggled in league matches and could start on the bench.

What Hibs are saying: “The boys will go into Saturday knowing we can do it again and I am buzzing for it. I think we are due a wee bit of luck and hopefully we can get that and break the Hampden curse. Everyone seems to say Hibs have bottled it in big games. I would love to go out on Saturday and just prove everyone wrong.” (Jason Cummings, Hibs striker)
What Dundee United are saying: “The history for Hibs as a club in the Scottish Cup has not been too good. One day it will change. But this is a huge match for us, a chance to get to the Scottish Cup final, which is always a wonderful day. Any player wants to play in cup finals and win trophies. Winning this would give us a chance. We don’t think about the league at all at this moment, we’re fully concentrated on the Scottish Cup.” (Mixu Paatelainen, Dundee United manager)
