The on-loan Chelsea man has been ruled out for three to four weeks with a groin strain and will therefore miss out against the Robins, but experienced left-backs Marcus Hall and Jordan Clarke are both available to step in.
Hall has recovered from the knee injury sustained during his testimonial against Everton at the start of the season while Clarke will be in confident mood following his recent debut for the England Under-19's.
Otherwise, Coleman has no other new injury or suspension concerns, with winger Michael McIndoe set to come up against his former club.
Keiren Westwood, Leon Best, Sammy Clingan and Aron Gunnarsson are all okay following their international exploits.
That just leaves winger David Bell (ankle), defenders James McPake (shoulder) and Elliott Ward and goalkeeper Danny Ireland (emergency bowel surgery) as long-term absentees.
