Joe Edwards and James Wilson are pushing for recalls following spells out with injury ahead of tomorrow's home game against Scunthorpe United (3pm kick-off).
Vice-captain Edwards has been sidelined since the 1-0 defeat at home to Gillingham with a hamstring problem, while Wilson has not played in a month with an ankle injury.
The on-loan Sheffield United centre-half has trained all week - but manager Whitney admits he has a selection headache at centre-half with youngster Kory Roberts impressing in Wilson’s stead.
Florent Cuvelier also came through 80 minutes for the Developmental Squad this week in their 3-1 win at Rugby Town in the Birmingham Senior Cup.
“We’re okay and I’ve got a fully-fit squad - Joe was back with us on Thursday and Willo (James Wilson) has trained all week,” said Whitney.
“Callum Cockerill-Mollett is doing really well with his rehab, too.
“It’s a good place to be. We’re trying to take the momentum from the last two League games and if we can we’re in a good place going in the festive period.
“Of course Kory’s form has given me a selection headache. All you can do is keep your attitude right and take your chance when it comes.
“With Kory, whenever he has come in, he’s done well and impressed. Experience is important but for James, that doesn’t give him a divine right to come back in.
“I have to weigh up the opposition and look at how they train today before I pick my team for tomorrow.”
Scunthorpe currently sit third in the Sky Bet League One table, having won their last five League games and sitting just two points behind Shrewsbury Town in second.
And Whitney wants his side to make life as difficult as possible for United this weekend.
“We’ve watched their last two League games and went to Doncaster on Sunday,” said Whitney.
“They don’t change the way they play - they’re aggressive and have a high-tempo style of football.
“They’ve got great ability and abundance up top, and experience at the back with McArdle and Burgess.
“They have a couple of injury concerns but we expect their A-game. Graham (Alexander, Iron manager) will be coming here wanting to get a result and we have to make sure that we make it difficult for them.”
