LONDON (AP) " West Ham's record signing Andre Ayew is out for four months with a thigh injury.
Club chairman David Gold tweeted Thursday: "Sad news. Ayew has injured his quadriceps and will need surgery. He will be out for 4 months. Good luck Andre."
Ayew was injured 35 minutes into his debut in West Ham's 2-1 defeat at Chelsea on Monday in the English Premier League.
The 26-year-old Ghana forward signed for West Ham for a club record of 20.5 million pounds ($27 million) on Aug. 8.
Ayew, who joined on a three-year deal with the option of two more years, played alongside current West Ham star Dimitri Payet at Marseille.
