Dakar - Hannover 96 striker has suffered an injury while on international duty with Senegal.
Out of Bayern clash
The 25-year-old injured his right ankle in his country's 1-0 2014 FIFA World Cup qualifying victory over Uganda on Sunday evening and was replaced with 15 minutes of the match remaining.
The extent of the injury has yet to be determined, but Diouf is almost certainly going to miss die Roten's trip to Bundesliga champions FC Bayern München this coming Sunday.
Diouf has scored two goals this season for Hannover, who are currently enjoying their best start to a campaign in 48 years.
