Arsenal have suffered a heavy injury blow for William Saliba.
The 21-year-old limped off against Sporting Lisbon in the Europa League last-16 clash and had to be replaced by Rob Holding.
Now, reports in France suggest his absence from the first team could be long term.
L'Equipe reports the centre back could be missing for "several weeks", and is set to withdraw from international duty.
Saliba was due to link up with the France squad for matches against the Netherlands and Ireland.
However, he will now be set for an extended period of time on the treatment table as he aims to recover for Arsenal's title bid.
