Four-day captain Paul Collingwood is in talks with Durham to extend his career beyond the 2015 county season.
Collingwood will turn 40 next May but has been ever-present for Jon Lewis's side so far this campaign, taking 11 wickets and scoring 552 runs.
The former England one-day skipper made his first-class debut in 1996.
"I'm really enjoying my cricket, the dressing room, still. I'm fit enough - I think - to get through another year," Collingwood told BBC Look North.
"I want to keep taking this club forward and it's important we build the right culture here for years to come and bring the youngsters through.
"There are still things I want to achieve, and winning things for Durham so it'd be silly to hang my boots up when I'm still enjoying it."
