Wolfsburg s Algerian international Karim Ziani is expected to be out for two to three months because he needs a hip operation, the Bundesliga club announced on Tuesday.
The 28-year-old, who arrived at Wolfsburg in July 2009, has struggled with a pain in his groin and needs an operation to fix the problem.
Experts consulted have determined that Karim Ziani could not do without a hip operation, said the 2009 Bundesliga champions on their website.
It is expected he will be out for two to three months.
The midfielder was part of Algeria s World Cup squad and despite 13 appearances, including three this season, for Wolfsburg, has yet to win a game with the Bundesliga club.
Wolfsburg, who are second-from-bottom of the German league, are at Hamburg on Wednesday in the German league.
