St Mirren manager Danny Lennon admits he may add Estonia international Sander Puri to his squad later this week.
The 24-year-old free agent has been training with the Scottish Communities League Cup finalists after failing to win a deal with Kilmarnock.
And Lennon revealed he would make a decision on the former KuPS player before Sunday's showpiece with Hearts at Hampden Park.
"We have had Sander in training and we will monitor him very closely," the Buddies boss said.
"We are always interested in good quality players and he certainly comes with that pedigree and has a CV to back it up.
"We like what we see so it's looking promising. Not just us, but it also gives him the opportunity to get a feel for our football club and make sure it's right.
"I wouldn't envisage a problem with that. We will monitor it in the next two or three days and then we will make a decision."
