Experienced centre back, Luke made 24 appearances for the Rams last season, 2 as sub and scored 2 goals. His confident presence in defence, since his return from injury, contributed to the team's progress in the second half of last season.
Manager Jon Underwood added, "Luke had a bit of a stop-start season before we came in due to injury but he was probably the most consistent performer in those final games, a real leader, and I'm delighted he has agreed to stay for next season."
