James Collins is a fitness concern for West Ham United after pulling up with a suspected hamstring injury in the friendly against Dagenham & Redbridge on Wednesday night.
The experienced centre-back lasted less than a third of the match at the Chigwell Construction Stadium before hobbling down the tunnel for further treatment.
United are already without Winston Reid for the rest of the season and Jose Fonte was offloaded to Chinese club Dalian Yifang a month ago.
Collins, meanwhile, has started 12 times for the Hammers in the Premier League this term, including in the 3-0 home defeat to Burnley last time out.
West Ham won the fundraising friendly 3-1 through a Michail Antonio brace and a goal from Jordan Hugill.
