According to Barcelona, it is a meniscus injury in the 32-year-old's right knee.
Suárez operated on his knee in May 2019, missing two league matches and the cup final against Valencia, but was back on the pitch just in time for this summer's Copa America where Uruguay reached the quarterfinals.
Barcelona lead the Spanish league, on as many points as the Real Madrid antagonist, and Luis Suárez has been recorded for eleven goals and seven assists in the season.
