BARCELONA, Spain (AP) -- Barcelona midfielder Rafinha has injured his right knee during Sunday's 4-1 victory at Granada.
The club said that 24-year-old Rafinha will undergo further tests to determine the extent of the injury to the meniscus in his knee.
The Brazil international asked to be substituted early in the Spanish league match. He walked off and was replaced by Paco Alcacer, who went on to score.
While awaiting the results, coach Luis Enrique said the injury to Rafinha ''is a big loss for us.''
Rafinha has scored eight goals in a mixed role as occasional starter and often-used substitute for Luis Enrique this season.
