Tony Mowbray’s team battled away against the more physical and direct hosts, and Blackburn finally got their rewards when striker Joe Nuttall scored with just five minutes remaining, before Adam Armstrong subsequently secured the three points with an even later finish.
Taking to Twitter, Lenihan claimed it was a 'brilliant win' for Blackburn against a tough side, and supporters were quick to show their appreciation for the defender’s battling display.

Rock solid today with Rodwell deserved man of the match #rock— dan thomson (@dthomson9) January 12, 2019
Great performance last night Darragh, future leader and captain for sure, nobody exhibits a greater will to win. Hard fought win against a horrible team, repeat of their performance at Ewood, extra bit of class from the bench won the day.— Ray Grimshaw (@Maroon_and_Blue) January 13, 2019

You were awesome today. Nuttall’s instinctive header was genius great work. Looking at the right end of the table again! Keep us dreaming lads ⚪️❤️#MowbrayHadADream— Daniel Astley (@Binder90) January 12, 2019
Best performance of the season from you today. Keep it up— Adam lodge (@lodgie34) January 12, 2019
Lenihan was a rock at The Den and was among the best players on the pitch, recording six aerial duels won and eight clearances which was more than double the number of Rovers’ next best.
The 24-year-old has started 23 of Blackburn’s Championship fixtures this season, and he had added responsibility at Millwall as he featured alongside Jack Rodwell - who was making only his sixth start this season.
The victory moves the Lancashire side back up to 14th position in the table, six points adrift of the playoffs.
Blackburn’s next two league games are at Ewood Park against Ipswich Town and in-form Hull City.
