Diarra came off the bench during the Black Cats’ 1-0 win over Fulham and quickly made an impact by assisting Wilson Isidor’s winning goal.
However, he was forced off shortly afterwards. Le Bris admitted his absence is disappointing, particularly after his impressive contribution against the Cottagers.
“Habib is out for about 6-8 weeks which is a shame after the impact he made against Fulham,” the manager said.
“It’s frustrating, but we have to manage it and we will find solutions.”
“It’s a shame because I was so pleased with his pre-season and he’s getting more mature about his game, about clarity on the pitch, about his qualities and how they fit with the demand of the Premier League.”
