West Ham United co-chairman David Gold says Andy Carroll could be back in action by September.

The 26-year-old has struggled for fitness since completing a £15million move from Liverpool to Upton Park in 2013 and has been ruled out since the start of this year with a serious knee injury that required surgery.

Gold tweeted:

Andy Carroll is training hard and getting stronger. We are hopeful that he will be available early September. dg https://t.co/ZXS0TAeubg — David Gold (@davidgold) July 14, 2015
