Millwall have no new injury concerns. Boss Neil Harris picked the same side for the eighth time in nine fixtures for the 2-2 draw at Ipswich on Monday, with the Lions now unbeaten in 14 league games.
Aiden O’Brien, Tom Elliott, Fred Onyedinma, Tim Cahill and Ryan Tunnicliffe are waiting in the wings should Harris opt to freshen things up.
Bristol City manager Lee Johnson could bring Callum O’Dowda and Matty Taylor back into his squad.
Winger O’Dowda had an injection in his ankle a few days ago and will undergo a second scan before he is passed fit. Striker Taylor is back in training after undergoing a double hernia operation in February.
