The midfielder misses the first of two matches following two bookable offences, and he joins Alan Judge on the suspended list.
Judge completes his own two-match ban on Saturday and will be available for County's final two matches of the campaign.
Kiwomya has no new injury worries but may be tempted to give a starting berth to striker Francois Zoko who was named on the bench for the defeat at Dean Court.
County are destined for a mid-table finish, sitting in 12th position 10 points adrift of the play-offs with three games to go.
