MILLWALL have named an unchanged team from the side that won at Middlesborough last week.
The Lions won 1-0 thanks to a goal from super-sub Romain Esse, who once again starts from the bench.
The victory was followed up by a rotated team crashing out of the Carabao Cup in midweek to Reading.
Rowett had made five changes for that cup match but has gone back to full-strength for today.
Last season’s Tom Bradshaw will be looking to get some time off bench and build on the four goals he has already scored against Bristol City.
The Robins have made two changes from the side that drew with Preston North End last week.
Joe Williams and Mark Sykes have come in for Andreas Weimann and Harry Cornick.
Millwall: 3-4-1-2: Sarkic; Hutchinson (C), Cooper, Wallace; McNamara, B Mitchell, De Norre, Bryan; Flemming; Watmore, Nisbet.
Substitutions: Bialkowski, Evans, Bradshaw, Leonard, Voglsammer, Emakhu, Saville, Esse, Harding.
Bristol City: 4-2-3-1: O’Leary; Tanner, Vyner, Dickie, Pring; Williams, James (C), Knight; Skyes, Wells, Bell.
Substitutions: Bajic, Naismith, Araoye, Knight-Lebel, King, Roberts, Mehmeti, Cornick, Yeboah.
