First-half goals from Derek Mazou-Sacko and Camiel Neghli helped Alex Neil's side climb to second place above Ipswich Town, which plays the first of its two games in hand against Middlesbrough later on Sunday.

Millwall was quick out of the blocks and hit the front after just three minutes, with Mazou-Sacko beating Joe Walsh from 20 yards after Femi Azeez's initial cross was only half-cleared.

It was 2-0 in the 17th minute after QPR failed to deal with another cross, and Neghli stepped inside a challenge before curling into the far corner.

The hosts went close to increasing their advantage, with Walsh making smart saves to deny Josh Coburn in both halves.

Nevertheless, the two-goal margin was more than enough to secure victory for Millwall, whose play-off spot would have been secured this weekend had Wrexham failed to beat Stoke City later in the day, but the Welsh side registered its own 2-0 win to keep its own hopes of a play-off berth alive.

"We made a fast start. We needed to get the fans behind us, we needed to play on the front foot, try and create chances and pressure," Millwall boss Neil said after the win.

"To score so early and to back that up with a few chances and another goal set us up really nicely for the remainder of the game. Delighted with the lads' performance."

Elsewhere, Derby County also kept its own play-off hopes alive with a narrow 1-0 win over relegation-threatened Oxford United, which remains 22nd on the table.

Jaydon Banel scored the only goal at Pride Park, where the Rams moved within two points of sixth-placed Hull City.
