Millwall are likely to stick with youth in the match at Crewe as they wave goodbye to the Championship on Sunday.
The relegated Lions overcame Burnley last weekend with a starting XI boasting an average age of only 21, and caretaker manager Alan McLeary is poised to persist with a similar formula.
McLeary is still without a number of senior players as he prepares to face a team Millwall will meet in League One next term.
Midfielders Alan Dunne (fractured cheekbone), Jody Morris (knee) and David Livermore (foot) are all out of action along with winger Josh Simpson and striker Barry Hayles (both knee).
Crewe manager Dario Gradi has doubts over Billy Jones and Darren Moss.
Like the Lions, Gradi is expected to give a number of youngsters a chance, including Nicky Maynard and Michael O'Connor.
Utility-man Jones is struggling with a dead leg and right-back Moss has a hamstring injury.
Goalkeeper Ross Turnbull has been recalled by Middlesbrough and Stuart Tomlinson will come into the side.
Striker Juan Ugarte (knee) and goalkeeper Ben Williams (illness) are set to return in pre-season.
