Jake Hesketh has left Saints on loan to join MK Dons.
The midfielder spent the first half of the season with Burton Albion before returning to his parent club in at the beginning of this month.
He will link up with former Saints player Paul Tisdale at MK Dons until the end of the campaign in order to boost their bid for promotion.
Tisdale’s side are currently sixth in League Two but have a game in hand over their rivals.
Hesketh, 22, scored three goals during his spell at Burton, including a fine solo effort against Saints’ fierce rivals Pompey.
