Barcelona's Brazilian midfielder was forced from the field against Athletic Bilbao following an accidental collision with his own goalkeeper
Barcelona midfielder Rafinha suffered a broken nose in his nasty clash with goalkeeper Marc-Andre ter Stegen against Athletic Bilbao.
The club confirmed the extent of the problem after the Brazil international was left bloodied on the pitch having been accidentally kneed in the face by the shot stopper.
Barca won Saturday's match at Camp Nou 3-0 to move within one point of leaders Real Madrid, although they have played two games more.
Rafinha had to be replaced by Ivan Rakitic early in the second half after receiving treatment for several minutes.
