The 31-year-old frontman recently confirmed an interest in signing for the Cappielow club and indicated that he would be willing to play for free. However, Shiels refused to be drawn on the subject when contacted by the Tele to ask if the possibility of adding Riordan to his squad was an option he would consider.
The Northern Irishman said: “I don’t want to comment on that or speculate on any names or individuals. I’m considering a lot of options but the situation with the budget is that players need to leave before others can come in.”
One player who has departed Cappielow in the last few days is 17-year-old development squad defender Glenn Eadie. The ex-Celtic kid has had limited game time with the reserves after stepping up from the Under-17s at the end of last season and left the club by mutual consent on Wednesday.
Shiels confirmed that the right-back was no longer a Morton player but stated that Eadie’s exit would not free up a space for a new signing.
He said: “We agreed to Glenn’s release, but that’s not to free up funds as he was one of our junior players.”
Eadie tweeted: “Through mutual consent, that’s me finished with Morton! Wish the lads all the best for the rest of the season and future!”
