Tony Mowbray spent just under three years in charge of West Bromwich Albion, and this weekend takes his current side to The Hawthorns looking for a fourth consecutive Championship clean sheet.
Rovers followed up back-to-back 1-0 wins against Middlesbrough and Hull City with a 0-0 draw on home turf to Cardiff City last weekend.
The midweek Carabao Cup clash with Sheffield United allowed Mowbray's men to take their eyes off the league for one night only, but it's back to the bread and butter of the Championship this weekend against Slaven Bilic's Albion.
It's been a decent start to life as a Baggie for Bilic following his summer appointment, with his charges unbeaten in their opening five league games so far, of which two wins came from that quintet of fixtures.
Bilic went about bringing reinforcements in the summer following a high turnover of players heading out of the door following the end of the 2018-19 campaign.
He lost goals following Dwight Gayle's return to Newcastle United and Jay Rodriguez's switch to Burnley, with the burden now on the shoulders of big money signing Kenneth Zahore.
Romaine Sawyers returned to the club where he started his career in the summer, and the playmaker will be the one to watch for the Albion. Ex-Rovers loanee Rekeem Harper could also start in midfield.
Rovers boss Mowbray has confirmed that Ben Brereton and former WBA loanee Tosin Adarabioyo will definitely miss the weekend battle through injury, but Greg Cunningham is expected to return to league action after being ineligible to feature against parent club Cardiff last weekend.
Rovers were unbeaten in both games against West Brom last season, with Harrison Reed leveling in the 1-1 draw in the Midlands, before two goals in the space of five minutes from Charlie Mulgrew and Bradley Dack earned a narrow 2-1 win at Ewood Park at the beginning of 2019.
Rovers have suffered just two defeats against The Baggies in the last seven meetings at The Hawthorns.
Kick-off on Saturday afternoon is at 3pm, and if you can't make the clash then you can track all the action on iFollow Rovers and our social media channels.
