Goals from Jake Cooper and Steve Morison earned Millwall a deserved 2-0 victory at rock-bottom Coventry City at The Ricoh Arena on Saturday afternoon.
Neil Harris made two changes from Wednesday night's goalless draw with Walsall, as Mahlon Romeo and Aiden O'Brien returned to the starting line-up at the expense of Shaun Cummings and Shane Ferguson, who both dropped to the bench.
An even start saw a lack of chances at both ends, but the first fell of the way of The Sky Blues in the sixth minute, as Ryan Haynes show weakly into the arms of Jordan Archer.
Haynes repeated the feat 25 minutes into a largely uneventful opening half-hour, with The Lions' first half-chance coming in the 27th minute, as Cooper's looping header eventually found its way into the arms of Coventry goalkeeper Lee Burge.
Millwall took the lead on 33 minutes. Morison stung the palms of Burge, forcing a corner. Shaun Williams swung his kick to the back post where he found a lurking Cooper - the defender has no qualms in slotting home for his first goal since arriving on loan from Reading.
Coventry almost got back on level terms shortly after, but Farrend Rawson's header was somehow deflected behind for a corner, before Marcus Tudgay narrowly shot over Archer's crossbar.
Two minutes from the end of the first-half, the lead was nearly doubled, as Gregory connected well with an O'Brien cross, but unfortunately, it nestled straight into the arms of Burge.
Jimmy Abdou replaced Ben Thompson at half-time and eight minutes into the second-half, indecision from Burge left the goalkeeper stranded outside his penalty area, but Gregory could not capitalise on the error, standing on the ball as he shaped to shoot. The Lions forced a corner, but Tony Craig headed over under pressure from The Sky Blues defence.
Chances were few and far between and with just under twenty minutes to go, Onyedinma replaced Gregory as Harris looked for a different option in attack.
Eleven minutes from time, the lead was deservedly doubled and the game all but put to bed, as Morison tapped home after Onyedinma's shot was saved by Burge.
Mark Heywood blew his whistle for one last time after three minutes of stoppage time - Millwall are now unbeaten in ten games and sit on the fringes of the League One Play-Off spots.
