Although the 25-year-old can be registered as a Ton player, under FIFA registration rules he is ineligible to feature for the club before the beginning of the 2015/16 season.

According to the rulebook, a player can sign for three clubs during a single campaign but is only able to play official first-team matches for two of those clubs.

In Tidser's case, he has already turned out for both Rotherham United and Oldham Athletic, with whom he spent time on loan, and is therefore ruled out of playing for the Ton.

In a statement released tonight, Morton said: "We are extremely disappointed to confirm that we have been unable to finalise the registration of Michael Tidser at this time.

"Article 5.2 of the FIFA regulations regarding the status and transfer of players states that: 'Players may be registered with a maximum of three clubs during one season. During this period, the player is only eligible to play official matches for two clubs.' "Michael played 27 minutes for Rotherham in a league match at the start of the season before joining Oldham on loan. As Michael played for both Rotherham and Oldham this season and as the situation stands, Morton are able to register him as a player, however he would be unable to participate in first team matches for the remainder of this current season. This was confirmed when the club applied for international clearance for the player yesterday.

"Chairman Douglas Rae, who has been instrumental in trying to engineer Tidser’s return to the club, said: 'We will continue to look at all of the options regarding Michael’s future with the Club and I hope we are able to reach a satisfactory outcome.' "The player will therefore not be eligible for selection for tomorrow's match here at Cappielow against Dunfermline Athletic."
