Arsenal manager Arsene Wenger has confirmed that defender Gabriel Paulista will be out of action for six to eight weeks with a serious knee injury.
The 26-year-old centre-back was expected to miss this Saturday's FA Cup final against Chelsea after suffering the problem during last weekend's 3-1 victory over Everton on the final day of the season.
Now, though, it seems that the Brazilian is in danger of missing the start of pre-season as scans have discovered that he damaged his medial knee ligament.
It is a blow for Arsenal, who are already without defender Laurent Koscielny after his red card was upheld by the Football Association, meaning that he will serve a three-match ban.
The Gunners could end the season with silverware, but they failed to secure a Champions League spot for the first time in 20 years, eventually settling for fifth.
