Hull KR forward Jamie Langley admits no one is safe from the drop in Craig Sandercock’s side.
The ex-England forward will make his 250th Super League appearance tonight when they host Warrington Wolves.
But coach Sandercock has left out vice-captain Kris Welham after the long-serving England Knights centre was especially off-colour in their embarrassing 54-12 loss at Castleford.
The East Yorkshire club has had nearly two weeks to “stew” on that defeat and Langley told The Yorkshire Post: “Rovers have probably not had this depth in their squad before.
“Sandy has shown if he wants to change things he will and he’s not scared to drop anyone.
“It’s not great when that happens to a player but it gives someone else an opportunity to prove themselves and keeps everyone else on their toes.
“We know if we don’t perform someone else will so hopefully it will bring the best out of us.”
Langley, enjoying his first season at Craven Park having moved from Bradford Bulls, said: “It’s going to be a really tough challenge versus a Warrington side that has just beaten Leeds, got in the Challenge Cup semis and started hitting their straps.
“But we won over there earlier in the year and that was only a week after pushing them close here into the Challenge Cup, too, when we felt unlucky.”
Meanwhile, mindful Hull FC coach Lee Radford admits his side will not show Widnes Vikings “disrespect” again.
The sides meet for a second time this season when the Airlie Birds head over to Widnes desperate to get a win that would alleviate worries about being dragged into the relegation mire.
But they have been hurt by the Challenge Cup semi-finalists in the past, falling 7-0 at the KC Stadium in March.
“Earlier on in the year we probably did them a little disrespect, probably expecting the result,” said Radford.
“Watching the results of late, they’ve got some key players who are in really good form – Ticks (ex-Hull FC second-row Danny Tickle), who we know all about – a fantastic player and competitor – and Kevin Brown who is playing superb.
“It beggars belief how he hasn’t made the England squad.”
Castleford second-row Weller Hauraki, 29, will join Salford Red Devils at the end of the season.
