Barcelona playmaker Andres Iniesta has a bruised thigh and will miss Wednesday's Champions League Group H match at AC Milan.
Iniesta sustained the injury in Saturday's 4-0 La Liga win against Real Zaragoza and is being rested as a precaution, Barcelona said on their website (http://www.fcbarcelona.com).
He joins suspended full back Daniel Alves and fellow casualties Adriano Correia and Ibrahim Afellay on the sidelines.
There was better news for coach Pep Guardiola concerning forward Pedro, who has recovered from an ankle problem and is in the squad for the trip to Italy, Barcelona added.
Group leaders Barcelona and second-placed AC Milan qualified for the knockout round with two games to spare and a win for the Spanish club at the San Siro will secure them top spot and a potentially easier passage in the last 16.
Barcelona have 10 points from four matches and Milan eight.
