JAMIE Devitt and Tom Naylor are unlikely to return – but Grimsby Town's bosses could yet bring back Marcus Marshall.
The trio of loan signings – along with Cleveland Taylor and Dougie Wilson – returned to their parent clubs following the play-off semi-final defeat at Newport.
Since then, utility-man Naylor has been made available to other clubs by Derby County boss Nigel Clough, despite having a year left on his contract at Pride Park.
Devitt has been released by Hull City, while fellow winger Marshall sees his current deal at Bury end this summer.
Mariners joint boss Rob Scott says Devitt won't be heading back to Blundell Park after failing to make an impact in his second loan spell at the club.
"I have to be honest – we're not going to pursue anything with Jamie," he said.
"I don't think Jamie ever really got going. He didn't show us enough to warrant a starting berth week-in, week-out.
"We saw glimpses, but never enough over the period of time that he was here."
Naylor, however, impressed with his displays at centre-half and in central- midfield over the final two months of the campaign.
On the 21-year-old, Scott continued: "Tom is on very, very good wages at a Championship club and we got him at 75 per cent less than he was earning there.
"So it's unrealistic to say that we can sign him because what we could afford to pay is probably less than half what he's on.
"He's got another year left at Derby, so why would he walk away from what is a very good contract to something that's not as good at a lower level?
"That's where the loan market is good. People question it, but you can pick up players for a lot less than they're on at their parent club.
"We would love to have the likes of Tom Naylor at our club but that's probably not going to happen."
Having joined on loan in November and turned down a transfer to Luton in January, Marshall was a regular first-team pick until the closing weeks of the season.
"Marcus had a good run for us but he tailed off towards the end which I think he would agree with himself," said Scott.
"Marcus is contracted to Bury until the end of June and we wouldn't be able to offer what he's earning there.
"So it would be foolish of us to try to offer him something now, and him to breakaway from that for less money.
"We've got to be prudent. Marcus may be one of those that we revisit but Paul (Hurst) and I don't envisage any number of signings to be made until later on."
