Defender Maicon has failed to recover in time to be named in the Roma squad to face CSKA Moscow on Tuesday.
The Brazil international has not featured in over month due to an ongoing injury problem and despite suggestions that he could return for this decisive Champions League clash, Head Coach Rudi Garcia has not included him in his final selection.
