Defender Neill Collins is to return to Charlton Athletic for a second trial spell - but only after Dumbarton are safe from relegation.
Neill Collins has been watched by several top clubs
The Sons are one point ahead of second bottom Stranraer in Scotland's Division Two.
And manager Brian Fairley said: "Charlton wanted to see Neill playing in a game.
"But the player and ourselves have agreed that it is better for him to stay with us until the end of the season."
The 19-year-old Collins was with the English Premiership club for three days at the beginning of April.
He returned to help Dumbarton to a 2-2 draw away to Hamilton Academical on Saturday.
