Goalkeeper Mitch Walker has agreed a new one-year deal to remain at the club.
The 25-year-old played 16 times in the National League last season as well as in the two FA Cup matches against Cambridge United.
The former England C man was one of the nine players from last season’s squad who had been offered new deals to stay at Crabble.
Assistant boss Jake Leberl is delighted Walker, who signed for Whites from Brighton & Hove Albion in May, 2012, is remaining at the club.
Leberl said: “Mitch has been a pleasure to work with since he arrived.
“His professionalism, work rate and attitude has always been first class and to top it off, he’s a top goalkeeper who is improving year on year.
“We are all delighted he’s agreed to stay.”
As for Walker himself, he’s looking to put his frustrations of last season behind him and focus on the future.
He said: “I have enjoyed all my previous seasons at Dover although last year was frustrating for me on a personal note as I did not play as much as of course I wanted.
“I want to play regularly in this league, and I had offers to go do so elsewhere, but after speaking to the management here, I will get that opportunity at Dover next season – my aim is to play every game.
“The club is heading in the right direction and the ambition here has not changed since the day I arrived.
“It’s something I want to be part of and I am looking forward to pushing on from where we finished last season.”
