The Scottish Football Association has promised to back Celtic in their endeavour to be reinstated in the Europa League.
The Hoops lost 3-1 on aggregate to FC Sion in their play-off tie but with the Swiss side having signed five players they should not have because of a transfer embargo, the Scottish giants could win back their place in the European competition.
Uefa president Michel Platini has already condemned Sion's breach of rules and the Scottish FA has now pledged to give its support to Celtic.
"Celtic made contact with the SFA, as any member club would do, and the SFA have been backing Celtic," said president Campbell Ogilvie.
"The case is being heard this week and as a governing body we would always back one of our clubs in one of these cases.
"If there is a breach of rules, then Uefa will certainly take whatever sanctions necessary, but the SFA would certainly back a member club in this case.
"The nature of football now, with regulations and legalities, means it is quite a complex issue. I haven't been involved in the detail of it but it is quite evident that there are a lot of legal issues being addressed, but these will be heard this week I believe.
"The decision is for Uefa but if someone has breached regulations and has been proved to have breached regulations, then obviously a sanction should be taken, but that's obviously outwith our remit."
Celtic captain Scott Brown too is hopeful that Uefa will make a decision in their favour.
"They played three players who shouldn't have been allowed to play and at the end of the day you can't do that, and hopefully Uefa can see that as well," stated the midfielder.
