Philippe Mexes and Bologna's Gaston Ramirez have been suspended, meaning the Uruguayan will miss the game with Juventus.
The two players were booked during Roma's 1-0 victory at the Dall'Ara last night.
Mexes has only just returned from a two-match ban for insulting officials, but is sidelined again for the match with Parma.
Bologna lose creative figure Ramirez for their crunch tie against Juventus this weekend.
