Tony Mowbray was pleased with a "resilient" Rovers, who made it two wins from their last two games after the latest three-point haul away to Nottingham Forest.
After Joe Rothwell's scorching strike just before half time, Danny Graham's 150th career league strike - and 15th of the season - made things more comfortable for Mowbray's men.
But Martin O'Neill's hosts battled back and responded instantly through midfielder Ryan Yates after an error from David Raya.
Rovers had to show their mettle and character to defend stoutly after missing chances late on, and managed to see the game out professionally to earn the points at The City Ground.
“I think we just about deserved the win," the boss told iFollow Rovers after the final whistle.
“In Rothwell, [Adam] Armstrong, [Bradley] Dack and Graham, I think there’s some real attacking menace for the opposition, which Forest felt today.
“Bar a goalkeeping error, we were pretty resilient, blocking things and getting the job done at a tough place to come, in front of a big crowd.
“The solidity with Lenihan in the team was there as well. For eight weeks we were brittle, and there’s no doubt in my mind that without him, after conceding, we’d have lost or drawn the game without him.
“Dack should have scored when one-on-one, Rothwell almost scored too, but we won’t analyse things.
“We’ll try and enjoy the next four games. I’m delighted but there’s lots to work on so we won’t get carried away, as I’ve said to the lads."
