West Ham will not appeal against the red card shown to captain Kevin Nolan against Millwall.
Midfielder Nolan was sent off just nine minutes into Saturday’s 2-1 derby win for a two-footed lunge on Jack Smith.
Manager Sam Allardyce felt the decision was harsh but has accepted he will now be without Nolan for the next three games.
“It would be frivolous because they won’t change their mind, there are far too many instructions going out to referees today,” he said.
“We have got the squad to hopefully compensate now, we’ll get someone to fill in.
“We didn’t do badly without him with 10 men so we should make sure we do all right without him with 11.”
