Rotherham United embark on another Championship campaign after winning promotion from League One last season at the first time of asking, albeit via a points-per-game method after the 2019-20 campaign was ended early due to the coronavirus pandemic.
The Millers have been somewhat of a 'yo-yo' club in the last few seasons, bouncing between the third and second tiers of English football over the last four years or so.
Their desire to become a Championship regular took a step in the right direction in their opening league fixture when they claimed a late 1-0 win over fellow League One promotees Wycombe Wanderers.
Boss Paul Warne has penned a new deal this week to stay at the club until 2023.
Millwall – who are what you would call a Championship regular, having spent eight of the last 10 seasons in the division – started their 2020-21 campaign off with a goalless draw at home to Stoke City.
The Lions finished eighth last season, missing out on a playoff spot by two points.
The club have bought well and kept its key players ahead of another charge at the top six this term.
Rotherham United vs Millwall Head-to-Head
The hosts have had a successful period of late against Millwall, going unbeaten in their last four match-ups, winning three of those.
The pair last met in February 2019 when they both played out a 0-0 draw.
Rotherham last lost to Millwall at home in September 2006 in League One – something Saturday's visitors will want to amend.
In fact, the Millers have not lost to the Lions in the Championship since its re-branding in the 2004-05 season.
Millwall did have the better of Rotherham in earlier years, though, which sees the all-time record against one another stand at 13 wins apiece with 10 draws shared between them.

Rotherham United vs Millwall Prediction
Rotherham may have had the better of their opponents in the last few years, but this is a very different Millwall side under the guidance of boss Gary Rowett.
He's been able to turn losses into draws and draws into wins during his tenure and, as a result, has created a well-weathered squad.
The Millers have the comfort of their own ground to play in for the first time this season, but that may be all they get on Saturday afternoon.
Prediction: Rotherham United 1-3 Millwall
