Rovers are currently in eighth and just three points off the playoff positions, while QPR sit in 17th position, four points above the relegation zone.
Blackburn started 2021 in mid-table and eight points adrift of the playoff spots, but a run of good form, combined with Bournemouth's recent slump, means they could now break into the top six, and they also have a game in hand over the Cherries and seventh-placed Middlesbrough.
Rovers have won three out of their last four games and kept clean sheets in all of those victories, most recently beating Luton Town 1-0 last weekend.
Adam Armstrong scored his 17th league goal of the campaign in the 85th minute against the Hatters, proving not for the first time this season that the Lancashire side have a knack of grinding out results.
A goal difference of +13 also helps their cause in the playoff race, largely down to their 41 goals scored – the second most in the division behind Brentford. Meanwhile, no team has scored more goals away from home than Blackburn (21).
Rovers have won six of their last seven meetings with QPR and have only lost once to the Hoops in their 18 encounters this century; Tony Mowbray's side were 3-1 winners in the reverse fixture at Ewood Park in November.
Thet defeat marked the start of a run of just one win in 12 games for the West London side, but they have turned their form around in recent weeks.
Like Blackburn, QPR have won three out of their last four matches, with their 2-1 victory away to promotion-pushing Watford on Monday being the most impressive of the lot.
Mark Warburton's side had to come from behind against the Hornets, with the winning goal from Albert Adomah – his first for the club – arriving in the 90th minute.
QPR now return to the Kiyan Prince Foundation Stadium, where they have lost five out of their last six games and not won since November.

Warburton could name the same team that started against Watford, but the QPR boss says he is keeping an eye on the fitness of new signings Stefan Johansen and Charlie Austin, as well as Lee Wallace, who has just returned from over a month on the sidelines.
Macauley Bonne is expected to be fit after coming off against Watford with cramp, while Lyndon Dykes should be back in the squad after missing the game at Vicarage Road due to a family member testing positive for coronavirus; deadline-day loan signing Sam Field may also play a part.
Blackburn have signed centre-back Taylor Harwood-Bellis on loan from Manchester City, but Mowbray may be hesitant to make changes to a defence that has looked solid in recent weeks.
Queens Park Rangers possible starting lineup:
Dieng; Dickie, Cameron, Barbet; Kane, Ball, Johansen, Wallace; Chair; Austin, Bonne
Blackburn Rovers possible starting lineup:
Kaminski; Nyambe, Lenihan, Braithwaite, Douglas; Travis, Rothwell, Dack; Elliott, Armstrong, Gallagher
We say: Queens Park Rangers 0-1 Blackburn Rovers
Both teams will be eager to continue their recent good form so a tightly-contested match should await. However, Blackburn's tight defence, combined with QPR's poor record on home turf, makes us think that the visitors will take the points here.
