The former Hearts defender could be the final piece in McCoist's transfer jigsaw.
A successful summer shopping spree has seen nine new arrivals at Ibrox in recent weeks as the Blues boss transformed his squad into one of the strongest in the country.
McCoist has had plenty problems to solve during the most turbulent time in Rangers' history, but now he is presented with a welcome conundrum as he attempts to mould his bulging squad into an impressive team.
CHRIS JACK looks at McCoist's options and where those who report for first team duty are likely to fit in this season...
FIRST NAMES ON THE TEAM SHEET
RANGERS may have been in fine form on League One duty so far this term, but it has been a disruptive few weeks in terms of McCoist's team selections.
The Gers boss has been unable to unleash his new stars in the opening month of the campaign before the Gers' registration embargo expired on September 1.
With a full squad now available for selection, McCoist must find his strongest starting XI, something which could take a few weeks as players settle into life at Ibrox and the boss tinkers with his side.
The No.1 jersey will belong to Cammy Bell, with the former Killie keeper replacing Neil Alexander between the sticks.
He has enjoyed an impressive start to his Light Blues career and has the potential to keep the Ibrox gloves for many years.
In front of Bell, McCoist is likely to field two summer signings and two Ibrox stalwarts as his back four. Richard Foster has started at right-back in the wins over Queen of the South and Forfar in the last week and appears to be the first choice for that position on his return to the club.
On the other flank, Lee Wallace will be challenged by second-time Ger Steven Smith.
The Scotland international has been one of Rangers' most consistent and classy performers in recent years and should be a first pick in the weeks to come.
At the heart of the defence, Lee McCulloch and Bilel Mohsni have formed a solid partnership this far, seemingly solving Rangers' lack of physical presence and strength from last season.
The pair have been a threat at the other end of the park as well as McCulloch continues to lead by example and Mohnsi shows signs of becoming a fans' favourite.
The arrival of Marius Zaliukas would threaten both their places, but the Lithuanian would have to shine to dislodge the pair if he does eventually sign.
It is in midfield where McCoist has the most options but also the most dilemmas. Nicky Law has made an immediate impact since joining from Motherwell and will be a huge asset to the Gers this season.
But it is who partners him - with Lewis Macleod, Ian Black and new Ger Arnold Peralta all in contention - that McCoist must figure out.
First-team football is crucial for Macleod's development while Black started the campaign well before he was hit with a three-match ban for breaching betting rules.
Peralta has been used wide on the right and centrally thus far and could be the Light Blues' midfield enforcer. Someone is likely to have to miss out, though.
The same can be said of the Light Blues forward line. Despite Nicky Clark's prolific season for Queen of the South last term, McCoist has opted for Jon Daly to lead his attack thus far, with Andrew Little then supporting from wide or alongside the Irishman. Rangers have netted 34 times already this term and, despite McCoist not getting the extra striker he was after, the champions will certainly not be short of firepower.
WAITING IN THE WINGS
MANY of the players who took Rangers to Third Division glory last season are likely to find their chances limited this time out after McCoist overhauled a squad that often flattered to deceive in our bottom tier.
Injuries to youngsters Ross Perry, Chris Hegarty and Kyle Hutton could not have come at a worse time as they have fallen down the pecking order while even established first-team stars like David Templeton and Dean Shiels have a fight on their hands to win a regular Light Blues jersey.
The forward pair have had auspicious starts to the campaign following respective injury worries over the summer yet both have what it takes to add more quality to a strong Ibrox attacking arsenal.
Chances to impress could be harder to come by for Robbie Crawford and Barrie McKay while Kyle McAusland will see Foster's right-back berth as his best chance of a regular start and Sebastien Faure and Emilson Cribari will fight it out to be central defensive understudy.
McCoist's latest signing, Steve Simonsen, provides an experienced back-up to Bell and while Steven Smith has been used wide on the left and deep in central midfield, fans would prefer a more natural fit and for the left-back to focus on challenging Wallace for his place.
SEATS IN THE STANDS
WITH spaces on the bench in short supply, several players will have to settle for a loftier view of the action in the months to come.
Youngsters Luca Gasparotto, Andy Murdoch and Tom Walsh have all tasted first-team action but will have to wait for their chances to impress while fellow Murray Park kid Fraser Aird has fallen well down the pecking order.
Loan moves for Scott Gallacher and Andy Mitchell, to Airdrieonains and Annan respectively, should prove worthwhile, but both are some way from challenging for a regular starting slot.
