Bradford Bulls overcame fatigue to clinch victory over Crusaders in a closely fought contest at Odsal.
Dave Halley scored for the Bulls before Weller Hauraki and Vince Mellers crossed the whitewash for Crusaders.
Bradford's Chris Nero then latched onto a loose kick to touch down before Glenn Hall regained the lead for Bulls.
Michael Witt's boot kept the Welsh side in touch, and two penalties after the break gave them the, lead but Michael Platt's try sealed the win.
Bradford coach Steve McNamara said:
"I've never been as annoyed as I am with the team's performance, simply because it's extremely difficult both physically and emotionally after [drawing with Leeds at Headingley on] Thursday night.
"We were starting the game with - as much as we tried to fill the tank back up - half a tank of petrol, against a team who had a full tank.
"You can still go a longer distance if you do some smart things, but we gave penalties away in possession, kicked balls out on the full, dropped kick-offs - all the basic things that we needed to do, we never did in that game.
"So to come through it is a great testament to the players but I'm very angry at some of the things they did to each other."
Crusaders coach Brian Noble said:
"With them having played in a tough game on Thursday it was always going to be a case that later we might have won it.
"We had a few opportunities to win and part of the learning process of this team is that we need to learn to take those opportunities to take the two points. But I thought we were the better team.
"I'm disappointed for the players because they really are working hard. You've got to give Bradford some credit because they hung on in there."
