Dons have completed the signing of defender Lee Hodson from Watford.
The 21-year-old defender joins on a one-year deal to become Karl Robinson’s fourth signing of the summer, and third in the space of a week.
A week earlier, the Dons boss signed Southampton midfielder Ben Reeves on a similar one-year deal before securing the signature of Jason Banton on loan from Crystal Palace.
The trio join striker Patrick Bamford on loan from Chelsea.
Hodson has played more than 70 times in the Championship for Watford after climbing the ranks at Vicarage Road.
And Robinson said he was delighted to get his man.
“Lee ticks every box of our transfer policy this summer,” he said. “He is young and ambitious but he also has a wealth of experience with over 70 starts in the Championship to his name along with nine full international caps - for someone of his age that’s a remarkable statistic.
“He’s somebody I’ve really admired for a long time. He already knows League 1 from his spell at Brentford last season and I believe he will add great competition for places in our defence.”
Hodson’s first taste of action came in the 1-1 draw with Plymouth Argyle at Home Park on Sunday.
There, he played 81 minutes before being replaced by George Baldock.
Ryan Lane put the home side ahead with a brilliant strike 13 minutes from time, before Daniel Powell rescued a draw for the visiting side with a deflected effort with four minutes to go.
