West Ham are investigating claims striker Andy Carroll and goalkeeper Darren Randolph were drunk on Tuesday afternoon following a club sanctioned night out on Monday.
Carroll and Randolph led the group to an Italian restaurant in Knightsbridge. The pair, along with injured left back Aaron Cresswell, were then spotted in Mcdonald's at 7am.
There were conflicting reports on social media the following day and manager Slaven Bilic will likely have questions for the pair.
The Hammers have lost five of their six Premier League games this season, including four in a row, and play Middlesbrough on Saturday in their new London Stadium home.
