Sevilla defender Sebastien Squillaci is set to undergo ankle surgery which will keep him out for another two weeks at least.
The France international was replaced during the Spanish side's 2-1 defeat to Atletico Madrid on January 2nd and the club announced the next day that he would be unavailable while he rested his ankle.
But, following discussions which involved French national team doctor Alain Simon, a decision has been taken for the central defender to undergo arthroscopic surgery and he will travel to Paris on Wednesday.
The club added Squillaci, who signed from Lyon in the summer of 2008, "could return to the pitch in a little more than two weeks if all goes well."
Sevilla have lost their last three league matches to sit in fifth in La Liga, 13 points behind leaders Barcelona.
