Gilmartin dealt harsh hamstring blow
The Dublin-born goalkeeper, 22, has only recently established himself as first-choice at the Banks's Stadium, starting the last nine games having previously had a bit-part role behind Clayton Ince.
But after grabbing his chance, he had to limp off during Saturday's victory over Exeter - leaving the Trinidad and Tobago shot-stopper to step in.
And scan results have now highlighted a 3cm tear in his hamstring that will keep him on the sidelines until the middle of next month.
