The experienced defender will miss the tie with a dead leg while the Robins will check on former West Ham striker Sam Baldock who suffered a kick to his Achilles.
Meanwhile head coach Sean O'Driscoll is unsure whether he will include winger Albert Adomah. The former Barnet man, whose future at the club is still up in the air, was left out of the squad that drew 2-2 with Bradford on Saturday and he may be left out again.
O'Driscoll has also confirmed that Stephen Pearson looks likely to require surgery on his ankle injury while Marlon Harewood will play for the Under-21s on Monday and looks set to be on the bench against the newly-promoted Gills.
