Millwall chalked up a fifth consecutive Sky Bet Championship win on Saturday afternoon as Gary Rowett's side defeated Reading by one goal to nil.
Jake Cooper scored for a second consecutive game in the 38th minute to win the game for The Lions at the Select Car Leasing Stadium.
Rowett made two changes for the trip, both enforced, as Shaun Hutchinson and Mason Bennett missed out through injury. Daniel Ballard - for his start since November - and Benik Afobe replaced them, whilst Hayden Muller and Tyrese Briscoe stepped up to the substitute's bench.
The Lions started well and fashioned two free-kicks in the opening moments, but both efforts from Jed Wallace struck the wall and went over respectively.
Tom Ince - The Royals' most likely point of attack - tested Bartosz Bialkowski following that, with the forward then curling an effort into the stopper's hands as the midway point of the half came and went.
Millwall were keeping possession well but were yet to find a final ball that would unlock the Reading defence - Billy Mitchell's cross on 23 minutes was nodded on by George Saville and almost into the path of Cooper, but the back-line were able to scramble away.
However, with seven minutes to play until the half-time break, the opener came. Danny McNamara's long-range effort was tipped over spectacularly by Luke Southwood, but from the resulting corner-kick, Cooper was able to rise highest and head home to break the deadlock.
John Swift ballooned an effort over from inside the area as Reading looked to get back into the game at the end of the first-half, with Lucas Joao the next man to make attempts to breach the Millwall defence at the beginning of the second-half, but to no avail.
Saville had to hack the ball clear from safety on the hour-mark, before Scott Malone's effort was blocked at the other end in a period of few clear-cut chances. Reading substitute Ovie Ejaria and Swift failed to trouble Bialkowski late on, with The Lions claiming a fifth successive success not long after.
