BULLS full-back Brandon Pickersgill may be asked to play in the halves against Sheffield tomorrow, and he admitted the difference between the two positions is vast.

That is where Pickersgill was named during the Challenge Cup defeat to Featherstone, and with Jordan Lilley serving the final game of his two-match ban, it could be the same again.

If John Kear does decide to use Pickersgill as a like-for-like replacement for Lilley, then he knows he could be in for a very different game to usual.

Talking about how a full-back has to adapt playing in the halves, Pickersgill admitted: "I don't mind and I'll do whatever's best for the team, but they're two very different skill sets.

"The main one is that you're sorting out the defensive line at full-back, whereas you're in that line at half-back, making tackles in the set of six rather than in one-on-ones.

"You're nipping from side to side at full-back and listening to your halves, whereas you're the dominant player on your side at half-back.

"I'm vocal anyway, but you need to be even more so in the halves."

Asked if Bulls are confident going into the Sheffield clash at the Keepmoat Stadium, after sub-par performances in their opening three matches of the season, Pickersgill said: "We've not had the best few games, but this is where it counts now.

"Pre-season didn't really matter and I thought we were a bit better against Featherstone.

"We've had injuries to two key players in Sam Hallas and Matty Dawson-Jones, and bans for Jordan Lilley and George Flanagan.

"That's four of your regular 17 missing, which will have an impact.

"But we've not been where we see ourselves, so Sheffield is a chance to fix up.

"We watched them play York in the Challenge Cup the other week and thought they went quite well, so we know we need to turn up at 100 per cent.

"But if we can bring a full 80-minute performance, we believe we should be fine this Sunday."
