Millwall manager Mark McGhee threatened his whole team with the chop after their 6-0 humiliation to Rotherham.
He said: "It was embarrassing, but we only won two of our first six games last year."
Irish international Richard Sadlier could be recalled to the starting line-up against Watford.
But his international team-mate Steven Reid will have a late test on his injured ankle, and Charley Hearn remains suspended.
