The ex-Watford stalwart is still not recovered from the muscle strain he sustained in the recent 2-0 loss at Burnley, but is back in training.
Millers chief Warnock, who said that he will utilise his squad resources in the next week, mindful of games against the promotion-chasing trio of Owls, Middlesbrough and Derby County, said: “There is only Lloyd missing from the squad and he’s training as well again.
“We had to wrap them up in cotton wool a little bit this week as we have so many lads coming back from injuries and we managed to get a shift out of them last week and the result was the correct one.
“With three games in a week against top sides, it is going to be very difficult for us and we are going to have probably to use the squad over the week.
“I don’t think it will be possible to keep a settled side as we are going to have to use fresh legs on the Tuesday and Saturday.”
Nile Ranger is continuing to train with the club.
