His goal on Saturday only confirmed just how important a squad player Jackson is, and manager Paul Jewell has been quick to praise the versatile defender.
Jewell said: "Jacko epitomises what this club has been all about – he has been here since we were in the Second Division, playing in the LDV and things like that.
"He has seen us grow and has been a major part of that. Whatever you ask him to do, he does to the best of his ability, he never moans or if he does, I don't hear or choose not to listen.
"Jacko is an example to all young players of how to conduct themselves on and off the pitch."
