Hibernian are in signing talks with midfielder John McGinn.
Although the 20-year-old is out of contract at St Mirren, Hibs would still need to pay the Buddies a compensation development fee.
The Scotland Under-21 international first featured for the Paisley side in 2012 and has gone on to make almost 100 senior appearances, scoring four times.
McGinn missed the end of last season after being injured in a training ground prank but has now recovered.
He was spiked in the thigh with a training pole thrown by Buddies captain Steven Thompson in April.
And McGinn subsequently took legal action against St Mirren.
St Mirren manager Ian Murray said a contract offer remains open for John McGinn to stay at the club.
He told BBC Sportsound: "We had a contract offer on the table for John before I got here, I think it's been on offer for well over a year now. It's still on offer.
"I've not seen John McGinn train at St Mirren, I've not seen him play for St Mirren and it's still the same as it was last week and I imagine it'll be the same on Monday morning.
"Until someone comes along and gives us enough money that we feel is acceptable to accept and move on, John McGinn will probably not sign for anyone."
