Preston will be hoping they can translate their away form into home form after winning 2-1 away at Huddersfield Town, while Millwall came from behind to gain a point at home to Barnsley.
Alan Browne's double was enough for Preston to make it three wins from four away games, as they came from behind to overcome Huddersfield Town.
In contrast, Preston have not gained a point or indeed scored a single goal at home this season, and this will concern Alex Neil as home form is starting to hinder any opportunity of breaking into the top 10.
Browne yet again proved his worth and will have done himself no harm as contract negotiations between the skipper and the club move forward. The Republic of Ireland international is among several key players in the final stages of their current deals at Deepdale.
Alex Neil may go into the Millwall fixture without his usual right-hand man Frankie McAvoy, who is self-isolating due to track and trace. Thirty-six-year-old Paul Gallagher was asked to do a stint in the technical area with Neil and Steve Thompson on Saturday, meaning that Gallagher vacated his place among the substitutes, with Tom Bayliss drafted into the matchday squad.
The Lions currently sit just outside of the playoff places and will be keen to compound Preston's poor home form, to break into the top six.
Millwall's away form stack up well against their hosts' struggles on their own patch too, winning three of their four outings on the road this term and only losing twice on their travels since February.
Rowett's men were held at home by Barnsley last time out, though, and will know that improvement is needed if they are to get back to winning ways at Deepdale.

Barrett could again go with the 5-2-3 formation that faced the Tykes, with Shaun Williams, Scott Malone and Alex Pearce all coming into the starting lineup, and Murray Wallace, Matthew Smith and Ryan Woods all dropping to the bench after Tuesday's 2-0 victory over Luton Town.
Kenneth Zohore is also in contention after he made a strong impression off the substitutes' bench on Saturday.
Alex Neil will need to decide whether to keep Alan Browne at wing-back or revert him to his normal position as a holding midfielder in a 4-4-2 formation.
Otherwise, Neil is expected to name an unchanged lineup for the trip to Preston.
Preston North End possible starting lineup:
Rudd; Rafferty, Bauer, Davies, Hughes; Pearson, Ledson; Potts, Browne, Sinclair; Jakobsen
Millwall possible starting lineup:
Bialkowski; Romeo, Hutchinson, Cooper, Malone; Leonard, Woods; J. Wallace, Smith, Mahoney; Bennett
We say: Preston North End 1-2 Millwall
Preston have not been able to get going at home, and in Millwall, they will face a real test. Millwall have only lost once away from home this season, and we expect them to come out on top and keep their good run going.
