Ireland Under-21 captain Conor Coventry will spend the rest of the season at MK Dons, having joined on loan from West Ham.
The midfielder joins the Milton Keynes side following a short stint at Peterborough, where he made 12 appearances this season.
Coventry will join up with Troy Parrott at the League 1 club as well as former Bohemians defender Warren O'Hora.
Central midfielder, Coventry, formerly worked with Dons manager Liam Manning while coming through the academy at parent club West Ham.
Coventry was recalled by West Ham from Peterborough, however, he remains down the pecking order at the east London club with Declan Rice, Mark Noble, Alex Kral and Tomas Soucek all currently ahead of the 21-year-old.
"I'm delighted to be here," Coventry said. "This is a club moving in a really good direction and hopefully I can help make a positive impact towards that.
"I know how the team plays and it’s something that suits me. I am a player who will always give my all and look to get on the ball, dictate play and help keep possession.
"I obviously know the manager from his time at West Ham. He is someone I trust and who really helped my development so I am looking forward to working with him again and hopefully I can repay his and the club’s faith with my performances."
MK Dons are currently fifth in League 1 and take on bottom-placed Doncaster on Saturday, where Coventry will be in line to make his debut.
