The Ivorian picked up the problem in training earlier this week and is now guaranteed to miss Newcastle's next two fixtures against Chelsea and Tottenham, and will be a doubt for the game against Aston Villa on February 23.
The 27-year-old has made 24 appearances for Newcastle this season and has taken the captain's armband in the absence of Fabricio Coloccini.
Alan Pardew's men currently sit eighth in the Premier League, but have just one win from their last seven matches in all competitions.
