Gregor Robertson and Jamie Lowry have signed new one-year contracts with Chesterfield
Roberston, aged 27, is recovering from an achilles tendon injury sustained at Hereford in April
He had previously been out for a year with a broken leg but had got back into the side to make 23 appearances before his latest setback.
Robertson said: “The club is standing by me and I do appreciate that so much.
Former youth-team player Lowry who had been out since October 2009 with a cruciate ligament injury, made just three substitute appearances late last season.”
Midfielder Lowry said: “I have been out a long time so I appreciate the support shown by the club. I am really keen to have a good pre-season so I can get back in contention.”
