West Ham United have confirmed Kurt Zouma sustained a hamstring tendon injury during Saturday's Premier League win over Chelsea.
The 27-year-old former Chelsea defender had a scan on Monday which revealed the damage, but West Ham did not put a timeframe on his return.
The centre-back has already started his recovery programme at West Ham's Rush Green training facilities.
Meanwhile, the club have also said Ben Johnson suffered a low-grade hamstring strain in the 3-2 derby victory.
"Everyone at West Ham United would like to wish both Kurt and Ben all the very best in their recovery," a club statement said.
