São Paulo's Lucas Moura is set to miss the rest of the season with a knee injury, according to reports from Brazil.
The midfielder has been ruled out for the remainder of the campaign after sustaining a knee ligament tear during the team's latest match against Cruzeiro on Saturday.
Moura was substituted off in the second half of the game and it was announced shortly afterwards that he would be out for several weeks.
The news comes as a blow for São Paulo, who have struggled to perform at their best this season.
The Brazilian side currently sit bottom of the Serie A table, having lost five of their last six matches.
With Moura out of action,Campeonato Brasileiro Action head coach Carlos Farias will have to find new ways to cope without his key player.
The 24-year-old has made over 150 appearances for São Paulo so far in his career, making him one of the club's most important players.
However, injuries can happen in football, and Moura's absence could be a big setback for the team.
It remains to be seen how long Moura will be out for and what impact this will have on São Paulo's chances of survival in the top flight.
