The news is a blow for Saints – Mane had been in outstanding form, scoring in the 1-1 draw with Chelsea and the 2-0 win over Arsenal on New Year’s Day.
Southampton do not now expect the midfielder to feature in the Africa Cup of Nations??although boss Ronald Koeman said he may travel to undergo tests with the Senegal medical??team.
Koeman said: “Maybe they will call the player to have a test or to see what exactly happened.”
Mane – signed from Red Bull Salzburg for ??10m in the summer – appeared to injure himself whilst celebrating his fine goal against the Gunners.
The arrival this week of Werder Bremen winger Eljero Elia, on loan for the rest of the season, now looks particularly timely for Saints.??
