Harry Smith has returned to Millwall for “personal reasons”.
Smith, 22, is on a season-long loan with Swindon, and has made 10 appearances this season.
And despite his current absence from the League Two side, Robins boss David Flitcroft hopes the striker can return to the County Ground.
He said: “Harry’s had a few personal issues that are ongoing.
“We have not really got the resources at the club to support that at the moment, whereas Millwall have.
“I have been in good contact with Neil Harris, who I get on fantastically well with, and Harry is back there sorting those issues out, they have got the support structure to do that.
“We will see how it goes over the next week to 10 days and see if Harry can come back where he is in a real state to play and move forward with us.”
Flitcroft continued to tell the Swindon Advertiser: “It’s two managers trying to work out what’s best for a player to get the player in a good place to be able to continue his loan for us.
“Unless the FA confirms it, which they certainly haven’t, then the situation is ongoing.
“If we can get Harry back here in a good place then that’s what we are going to try to do.”
Millwall signed Smith from Folkestone Invicta last summer.
