Clarets new boy Lloyd Dyer will not feature for the Clarets in this weekend’s Turf Moor clash with Rotherham.
The former Watford wide man is still being assessed and integrated into the group following just three training sessions since joining on a short-term deal last Monday.
And Dyche insisted Dyer knows the challenge before him to break into a squad that could extend their unbeaten run to nine league games against the Millers on Saturday.
“Lloyd now needs to top up physically,” explained the Clarets boss.
“The last few weeks have been a bit up and down for him, so his training had been affected by that.
“Plus, he needs to get to know the group and get a feel for what we’re about.
“He’s only had three days with us this week, so we will do some top up work with him to take him into next week and take things from there.”
Dyche, who swooped for the free agent last weekend, added: “Once I knew he was coming out of his situation at Watford, I had a chat with my staff about it and what role we thought he could play.
“He is different to what we have and I spoke to him and he is keen for the challenge.
“He gets it and he certainly doesn’t expect to come here and walk straight into the team. He knows he has to earn the right but he wanted to be part of that challenge.”
Meanwhile, defender Michael Duff and midfielder Dean Marney could again miss out as Burnley look for a victory that could lift them to second in the Championship.
Dyche explained: “Michael has a niggly calf and is touch and go, so we’ll wait and see on him.
“Dean has had a really awkward time with not a major injury, but he’s had a good few days with us on the grass with the physios, so he’s making good strides forward now and we’re happy with that.”
Finally, striker Ashley Barnes is set to begin full training again after nearly nine months out with his knee injury.

Dyche confirmed: “Ashley is coming on nicely and is just on the verge of beginning free training with the first team squad.
“We will be easing him in slowly, but he’s beginning to train normally, which is fantastic.”
