Antony Kay has signed a new one-year contract with the MK Dons following their promotion to the Championship.
It means that MK have been able to tie down the entire backline that kept a club-record 24 clean sheets in 2014-15.
"Last season was very special, getting promoted in the way that we did, and I'm excited to get started again," Kay, who featured in all but one of the Dons' league fixtures last season, told the club website.
"I enjoyed the celebrations but the hard work starts now - I'll be ready and raring to go when we're back in for pre-season."
Next season will be Kay's fourth with the Midlands side. The 32-year-old has featured 125 times and scored four goals since joining from Huddersfield Town in 2012.
