BURY have been rocked by two injury blows ahead of Saturday's crucial local derby against Oldham Athletic.

Top scorer Adrian Littlejohn is battling to overcome a flu virus while young defender Danny Swailes - in terrific form in recent weeks - can't train because of a knee injury.

It is a blow for Preece who is already without Steve Halford (ankle) and long-term casualty Matt Barrass, who has now had surgery on his leg problems and will be out for a further three months.

"It gives us one or two problems and I'll have a look at things before the Oldham match," said Preece.

"Maybe we'll have to change things round a bit. But the players that came in against Mansfield did well and they have given themselves a good chance of staying in the team."

Preece was watching his reserve team play Scarborough at Gigg Lane today. He has picked 11 different players to the ones who beat Mansfield on Saturday and he insists there is still time for players to force their way into the first team.

"I will be looking at a new system and at different players because there are still places up for grabs," he added.

"There are still things I'm not 100 per cent happy about and the chance is there for players to force their way in and to make it difficult for me to leave them out."

Preece faces a real selection dilemma ahead of the Oldham clash. He has to decide whether to stick with the kids like Jason Jarrett and Chris Armstrong, who did so well against Mansfield and ended the club's sequence of 10 games without a win, or bring back the established old guard like Darren Bullock and Chris Billy.
