He could be out for the season, leaving Jose Mourinho with a quandary for Sunday's game at Udinese and beyond.
"Maicon will play the last game of the championship to celebrate the scudetto," coach Mourinho told Italian television.
His towering frame and powerful runs have made the Brazilian stand out this term as possibly the world's best right back.

Antonio Di Natale is possibly out for the rest of the season after damaging knee ligaments in Italy's 2-0 win in Montenegro on Saturday while fellow Udinese forward Alexis Sanchez is suspended for Sunday along with defender Maurizio Domizzi.
Argentina's Diego Milito was also injured on international duty and will miss Genoa's clash at bottom side Reggina.
