Marseille could be without Igor Paixao for a period after the Brazilian winger was injured during Sunday’s 2-1 defeat by Paris Saint-Germain in the Classique.
The 26-year-old was taken off before half-time at the Velodrome, with Angel Gomes coming on in his place.
Marseille head coach Bruno Genesio said the club was still waiting for further information, although the injury appeared to involve Paixao’s ankle.
“I’ve not yet had an update, but it looks like it is (a problem with) his ankle,” Genesio told the media after the match.
The injury is another concern for Marseille following their defeat by Paris Saint-Germain, particularly because Paixao has become an important player for the club.
The winger had been linked with a move away from Marseille during the final stages of the summer transfer window. Sunderland were among the clubs reported to be interested in signing him.
However, Marseille’s ownership decided to keep the Brazil international after Genesio and chief executive Stephane Richard argued in favour of retaining him.
With several high-profile players having left and only limited recruitment completed, Paixao had emerged as one of the key figures in Genesio’s squad.
His potential absence would therefore leave the Marseille head coach facing an additional selection issue as the club assesses the extent of the ankle problem.
