Ian Evatt believes injured Bolton Wanderers duo Lloyd Isgrove and Shaun Miller need at most a fortnight of intense work before they can be considered to start for the Trotters.
Former Sheffield United and Crewe Alexandra striker Miller has made just substitute appearances since joining Wanderers at the start of September.
His last appearance for Bolton came in the EFL Trophy where he came off the bench to score against former side Crewe.
Winger Isgrove meanwhile has made just on substitute appearance for the Trotters, coming off the bench in the League Two defeat against Newport County.
Both are still out and have been put through a mini boot camp to get their fitness to the level desired by Wanderers head coach Evatt.
Though both players are progressing in their respective comebacks, Evatt believes it will still be between a week and fortnight before the duo can be considered to start for the Trotters.
He said: “I think they need another week of hard intense work to make them robust enough.
“I have said it many times, to play this way you have to be really fit. You have to be.
“The last three or four games we’ve averaged 65/66 per cent of possession, so that means you are having to work hard with the ball and without it, so you have to be robust.
“They are not robust enough yet to be thrown in because I don’t trust that they won’t break down. We can’t afford that to happen and we’ll give them the time they need, probably another week, two weeks max.
“Lloyd is ahead of Shaun at the moment but they are both doing really well. Shaun had another scan on his calf which showed more of a neural problem and had an epidural.
"It’s not like he’s giving birth but to numb down the nerve a little bit and to make it not so painful and he's doing really well.
"I would think a week to two weeks, they'll be ready to go."
