Granada, Spain (AFP) - Barcelona midfielder Rafinha looks set to miss his side's Champions League quarter-final tie with Juventus after suffering a meniscus injury in his right knee against Granada on Sunday.
The Brazilian had to be replaced after just 17 minutes as Barca ran out 4-1 winners at Nuevo Los Carmenes.
"Rafinha has an injury to the inner meniscus of the right knee. He will undergo further tests to determine the extent of the injury," Barcelona said in a statement.
"It doesn't seem like it is very serious, but it is something that will mean he misses the next few weeks," added Barca boss Luis Enrique.
"He will be a big miss."
Rafinha had become a key player in Enrique's switch to a 3-4-3 formation following a 4-0 thrashing by Paris Saint-Germain in the first leg of their Champions League last-16 tie.
He has had an unfortunate history of knee injuries, having missed the majority of last season to cruciate ligament damage.
Barca face a huge month in their bid for a second treble in three years.
As well as facing Juventus on April 11 and 19, they travel to La Liga leaders Real Madrid on April 23 that will likely decide the victors of this season's Spanish league.
