Moore rested top scorer Le Fondre at Bradford on Tuesday and has been criticised in some quarters by supporters.
But the Millers boss thinks the break will have done his frontman the power of good.
He told the Star: "He played 60 games last season, another 30-odd this time. The lieks of Rooney get a rest, comes back and score and nobody says anything.
"As a manager, you have to make decisions on what is right for the team and I thought it was. It gives him a break and hopefully he'll come out of the blocks on his return with all guns blazing."
Le Fondre will be back in contention against second placed Bury on Saturday whilst Ryan Cresswell, who did some warm up's with the side pre-match at Valley Parade but wasn't on the bench, should be back in the squad to face his former club.
Cresswell and trialist Jordan Robertson both played in a behind closed doors friendly yesterday lunchtime.
