Maarten Stekelenburg was hoping to make his comeback for Roma today, but is not in the squad to face Atalanta.
The Giallorossi take to the field in the 17.00 UK time kick-off at the Stadio Olimpico.
Their Dutch international goalkeeper has been out of action since he was accidentally kicked unconscious by Lucio during the 0-0 draw at Inter on September 17.
It was widely reported he was eager to get back on the field with a Petr Cech-style protective helmet.
However, Luis Enrique announced his squad this morning and Stekelenburg is not going to take part.
The Spanish Coach only ever names his side a few hours before a game in order to keep the players on their toes.
Roma squad: Borini, Borriello, Burdisso, Cassetti, Cicinho, Curci, De Rossi, Heinze, Kjaer, Bojan, Lobont, Osvaldo, Pjanic, Pizarro, Rosi, Simplicio, Totti, Jose Angel
