Arthur suffered a post-traumatic calcification at the level of the interosseous membrane and still feels pain. Therefore he is not eligible to play.
His physical conditions are being monitored daily by Juventus' medical staff. Even if Pirlo needs him against Porto, it won't be easy to recover the former Barcelona star in time for the game.
