The midfielder was replaced in the dying minutes of the 1-1 draw with Plymouth after suffering a gash to his knee.
Boss Martin Ling told the club's official website: "He has a hole in his knee that will need to be stitched. Saturday will be too early but there is no broken bones or internal damage."
It is another blow to Ling, who remains without Brian Saah as he completes his three-match ban following a straight red card against Bradford earlier this month.
Forward Ryan Jarvis is out for two months after suffering a fractured rib and a punctured lung in the draw with Northampton, while Ian Morris (Achilles) and Lloyd Macklin (broken metatarsal) remain sidelined.
