Defender Joe Wright and goalkeeper Louis Jones will remain with Rovers until the summer of 2019 after the club took up options in their current deals.
Wright said: "It's good to have another year added on to my contract, it's been enjoyable this season so it's pleasing to get it sorted nice and early.
"It can be put to one side now and we can all focus on the football side of things, it's been discussed for a while and the manager is happy with how I've stepped up this season."
Jones said: "I'm really happy, I get another year to try and prove myself and make that next step of fighting for a place in the first-team.
"I've been out on loan to Sheffield FC for three months and they played a big part of my development, it's matured me as a goalkeeper."
