Newcastle will take Paul Dummett back from St Mirren when his loan deal expires, so they can assess his progress.
Danny Lennon hopes to convince Alan Pardew's club to allow the Wales Under-21 to stay in the SPL for the rest of the season.
However, with injury worries mounting and an alarming slide down the Premiership table, Newcastle may opt to retain the player for the run-in.
The St Mirren boss told the Paisley Daily Express: "Paul is away back down to Newcastle to speak to the people there.
"They want to assess him when his loan deal expires and it’s up on Sunday.
"We’re actively looking to get Paul back up here but Newcastle are short of defenders at the minute. Hopefully, we can come to an arrangement.”
Dummett has made 19 appearances for St Mirren so far this season, scoring two goals against St Johnstone and Dundee United.
Meanwhile, St Mirren manager Lennon has said that he hopes to add a striker to his squad, after missing out on a loan deal for Sporting Kansas striker Dom Dwyer.
He said: "The forward area is a position where we feel we could do with a helping hand, given that Thomas Reilly is out of action through injury.
"We are actively looking to see if we can get someone on board but I have to stress that it must be the right person."
