As usual, it was a busy 31 days for Rovers, who secured deals for a few players, whilst there were also departures during a hectic month.
It was a quiet start to the month, with Rovers just about getting over a hectic match schedule just after the festive period.
Friday 5th January: The first deal of note sees Liam Feeney extend his loan deal at Championship side Cardiff City until the end of the season on day five of the month.
Monday 8th January: The first incoming - of sorts - sees Paul Downing put pen to paper on a long-term contract with the club after impressing on loan from MK Dons. Paul is still unbeaten in League One in Rovers colours this season and admitted his desire was always to stay at Ewood.
Tuesday 9th January: The first new capture sees Tony Mowbray bring in a familiar face as Adam Armstrong arrives on loan until the end of the season from Newcastle United on Tuesday 9th January. Both Tony and Adam worked together at Coventry City in the past and Armstrong was the first fresh signing of the window, adding pace and skill to the squad.
Tuesday 16th January: A week passed with little news of incomings or outgoings. The media team were sitting with their feet up and twiddling their thumbs. And then the news came.
Jack Payne was the latest arrival to pose with the classic, cheesy shirt shot outside the Senior Training Centre on another chilly Lancastrian morning. It was another loan capture until the end of the season, with Jack joining from Huddersfield Town.
Wednesday 17th January: Then the week really started heating up, with Sam Hart heading to League One neighbours Rochdale on loan a day later in a bid for regular first team football under ex-Rovers man Keith Hill.
Thursday 18th January: Joe Nuttall ensures he'll be at Rovers long-term by putting pen to paper on a three-and-a-half-year deal. "As a young footballer you work hard to get a long contract at a big club and I'm over the moon," Nuttall told iFollow Rovers.
Friday 19th January: It's time to get that scarf out again. The protracted transfer of Amari'i Bell - a man who Mowbray was chasing all window - is finally agreed.
After all those 'Announce Bell!' Twitter messages and GIFs, we finally managed to do it, with the left back signing an initial two-and-a-half-year deal from Fleetwood Town, who, incidentally, were the opponents just a day after he signed.
A delighted Amari'i says: "Blackburn is a massive club. When I heard there was interest I was thrilled. Our ambitions match and it was a simple decision.
"It's hard to say no to a club like this. Some will say they are too big a club to be in this league. They want to go up and keep progressing and that's exactly what I want to do with my career."
Friday 26th January: Another talented young Rover puts his signature down on a contract as teenager John Buckley - who's been with the club since he was six - agrees a long-term deal. Classic Tony leaning over player shoulder shot for the photo? Check.
Buckley says: “I've always wanted this to happen, as I've been at the club for such a long time and have really enjoyed my time here."
Tuesday 30th January: Elliott Ward heads on loan to MK Dons. A deal until the end of the season sees Elliott head south as the relegation-threatened Dons look to strengthen their defence. Ward will stay at the Buckinghamshire side until the end of the season.
Wednesday 31st January: Deadline Day. We're prepared. We know things will perhaps go into overtime tonight, a takeaway will be on the agenda, that's for sure.
Connor Thomson leaves by mutual consent at 2pm, allowing him the opportunity to move to another club in the first bit of movement of the day.
5pm sees another outgoing, with Scott Wharton making the move to League Two, joining Lincoln City on loan until the end of the season to gain further first team experience.
An hour later and Callum Wright opts to move to Leicester City for an undiclosed fee as the time until the deadline gets closer.
Five hours to go but Rovers get no further joy in the window and Mowbray's work is done.
And he's pretty happy with how it all worked out in the end, saying: "We’re okay, so I’m not panicking because we did our business early and the evidence is there.
"We’ve made decent signings; to see [Dominic] Samuel and [Joe] Nuttall and Corry [Evans] on the bench, it’s good. That will only get stronger as the weeks go on."
