Coach Peter Gentle said he would make changes after Hull FC's woeful defeat at Widnes Vikings on Saturday.
The Black and Whites were beaten 36-16 at the Stobart Stadium, despite leading 12-4 towards the end of the first half.
"It's not good enough," said a frustrated Gentle. "We need to make changes.
"I've got the same faces making the same mistakes over and over, so I can't stick with them any longer."
Hull had got off to a strong start when Richard Horne sent Joe Westerman over in the second minute.
Ben Galea crashed over after 27 minutes to extend the lead to 12-4 after Paddy Flynn's try had put Widnes on the scoreboard.
But the turning point came either side of half-time. First, Flynn intercepted Brett Seymour's pass and ran the length of the field to touch down. Then, after the break, quick tries from Cameron Phelps and Chris Dean put the Vikings in control.
Phelps added his second before Tom Lineham briefly gave Hull hope when he cut the deficit to eight with his first try of the season.
But Frank Winterstein and Gareth Hock pressed home the Vikings advantage to complete a comfortable win.
Speaking after the match, Gentle criticised his side for a poor completion rate and giving away too many penalties.
"We must be the most ill-disciplined side in the competition," he said.
"We're not even giving ourselves a chance.
"Our completion rate dropped to 43 per cent in the second half.
"It's hard work that's going to get us out of this.
"The players out there aren't getting the message so it's time to bring in some players that will."
