The Latics boss is short at the back after Kangana Lord N'Diwa returned to Bolton Wanderers following the completion of his loan spell, and Haining's hamstring injury - sustained during Saturday's match at Hartlepool - means he will step up his efforts to bring in extra cover.
Young starlet Haining made himself a mainstay at Boundary Park last term after coming into the first-team midway through last season.
The stopper is expected to be out for up to three weeks with the injury.
