MILAN — Inter Milan forward Marko Arnautović faces another month on the sidelines because of injury while teammate Carlos Augusto will also miss Wednesday’s match against Atletico Madrid in the Champions League round of 16.

Both players had to come off in Inter’s 1-0 win at Bologna on Saturday after sustaining injuries. They underwent medical tests on Monday.

“The Austrian (Arnautović) has suffered a muscle strain in the right thigh, while the Brazilian winger has a calf strain in the right leg,” the club said in a statement.

“The two Nerazzurri players will be reassessed in the following days.”

Inter — last season’s Champions League runner-up — visits Atletico with a 1-0 lead from the first leg, courtesy of a late Arnautović strike.

Italian media reported that Arnautović will likely be sidelined for a month but Carlos Augusto could return for this weekend’s Serie A match against Napoli.

The 34-year-old Arnautović, who returned to Inter on loan from Bologna in August, missed two months earlier this season with a hamstring injury.
