The Czech Republic international was stretchered off with a trapped nerve early on against Reading last weekend, an injury which forced him out of the midweek home defeat to Swansea.
He is nearing full fitness but, due to the nature of the problem, Albion will not risk his involvement at the Ricoh Arena unless he is 100%.
Chris Brunt, who has been out of late with a calf injury, is also on the road to recovery and could make an appearance against the Sky Blues although it remains to be seen whether the game will come too soon for him.
Otherwise, head coach Roberto Di Matteo has no new injury or suspension problems from Tuesday's 1-0 defeat at The Hawthorns.
Goalkeeper and captain Scott Carson is still struggling with the ankle injury that prevented him from linking up with England recently but he should be okay to continue. Long-term absentees James Morrison (heel), Ishmael Miller and Neil Clement (both knee) remain out.
