The early indications were not positive and after carrying out tests, Barcelona announced on Monday that Ter Stegen has a complete rupture in the patella in his right knee. The club later announced that he had a successful operation. He is now expected to miss the rest of the season as the Catalan club will now have to rely on Inaki Pena and Ander Astralaga to fill the void.
An update from the club read: "Ter Stegen underwent successful surgery this afternoon on a patellar tendon injury in his right knee, performed by Dr Joan Carles Monllau under the supervision of the FC Barcelona Medical Services at the Hospital de Barcelona. He will be unavailable for selection until he has fully recovered."
