JAMAICAN international Damion Stewart could earn a second invitation to train with Darlington.
The 24-year-old defender will return to the Caribbean on Monday after spending a fortnight on trial with Quakers, during which manager David Hodgson was undecided about him.
While the 6ft 2in stopper made a favourable impression during his short stay, Hodgson would like more time to assess the player, who has earned 20 caps for his country.
Stewart, who plays for Harbour View in Jamaica, is keen to make the grade in England and spent a fortnight on trial with Stoke City in November.
The gangly defender played in Wednesday's friendly win over Queen of the South, where he looked assured alongside David McGurk
"Damion is very strong in the air, his passing is quite good, although there are other parts of his game we need to look at," said Hodgson.
"We've had him over for a couple of weeks and he was only really half-tested in the Queen of the South friendly.
"We have been impressed with what we have seen of him, although there are parts of his game we are aware of and some we aren't, so it's very difficult to make a decision."
With eight central defenders at his disposal, Hodgson's mind may have been made up for him.
He said: "If we had to make a decision today I would have to say 'no', when you take into account the defenders we already have."
Hodgson will not be following up his interest in Canadian midfielder Michael Lupton. The 22-year-old was recommended to assistant manager Mark Proctor by Middlesbrough officials but he failed to impress.
A striker remains Hodgson's main priority and he has not ruled out renewing his interest in Lithuanian Grigalevicius Mindaugas and Slovenian Tomislav Misura.
Hodgson is keen to take another look at Mindaugas, who impressed on trial with the club earlier this season, while a family bereavement prevented Misura from training with Quakers last month.
Darlington have loaned youngster Andrew Bulford to Bishop Auckland.
