According to the French publication L'Equipe he will now miss the next two months of the season due to the knock.
The 24-year-old, who famously netted his country's only goal in their 1-0 win over France in this year's World Cup, has now decided to undergo an operation next week in order to cure the problem.
The Dakar-born star had missed the last two weeks in order to rest the injury, however the fortnight's break has failed to heal the injury.
News of Diop's operation comes as a massive blow for Lens, who have lost three of the last five match, as the side are currently struggling in mid-table in the Le Championnat.
