HOLDERS Hull KR will face Warrington Wolves in the Challenge Cup semi-finals, in a repeat of last year’s final.

The Robins ended a 40-year major trophy drought with their 8-6 victory at Wembley last June.

Warrington led until Tom Davies scored a 78th-minute try and Mikey Lewis struck the conversion.

In the other semi-final tie, St Helens will play fierce rivals Wigan Warriors.

The pair have previously contested six finals – each coming out on top three times – and most recently met in the Challenge Cup at the same stage four years ago with Wigan winning 20-18 on their way to claiming the title.

St Helens won a dramatic Good Friday derby 34-24 earlier this month.

Warrington and Hull KR are yet to play each other this season as February’s scheduled clash at Sewell Group Craven Park was postponed for the World Club Challenge.

With one of those two now guaranteed to make the Challenge Cup final, that round-two league fixture will have to be played in midweek.

Each semi-final will be played at a neutral venue on the weekend of May 9-10 – which are expected to be announced on Monday – with the Wembley final on Saturday, May 30.

Saints were the first side to secure their place in the final four when they beat Catalans Dragons 36-4 on Friday night.

Hull KR were similarly comfortable in dispatching York Knights the following day, 48-10.

Later on Saturday, Warrington scored three tries in the final 15 minutes to see off Leigh Leopards 24-10.

And Wigan Warriors also had to work hard for a 26-22 victory at Wakefield Trinity on Sunday.
