Blackpool have taken MK Dons defender Gary MacKenzie on loan until the end of the season.
The 27-year-old, who played under Alex Rae at Dundee and was signed on a pre-contract agreement by Paul Ince at Dons back in 2010, will now go straight into the squad for the game against Bristol City.
Meanwhile, Ince has revealed he is close to adding a new member to his backroom staff.
"The person we are looking at is a very, very good coach," he told the Blackpool Gazette.
"I like to do a bit of coaching myself, but mainly on a Thursday and Friday - that's when I come into my own.
"At the moment I don't think the players have been coached much.
"Sometimes, when you manage, you see players making mistakes and you ask them why? They tell you they haven't been told what to do."
The 20-year-old has seen his chances limited at the KC Stadium since Steve Bruce arrived in the summer.
He spent time with Burnley earlier in the season, but he now he has been snapped up by Blackburn as they look to mount a late charge towards the play-offs.
Stewart's agent Peter Morrison of the James Grant Group, confirmed that the deal had been concluded.
"He has signed a deal until the end of the season," Morrison told Sky Sports.
"This is a fantastic move and opportunity for him, to sign for a massive club such as Blackburn.
"They have huge ambition and highly respected top young manager and the chance for Cameron to be a part of that was too good an opportunity for him to turn down."
The Pilgrims have launched an initiative, titled ?BigForBarnet, which has seen entrance prices slashed and a number of deals introduced including free entry for children in a bid to pack out the ground.
And Sheridan, whose side head into the game rock bottom of the Football League, knows their form has to improve in front of their own supporters having overseen just one home win since taking charge.
"We need to be a lot better at home," he said. "We need to be courageous and brave and take charges. We need to be positive and get on the ball.
"We've been very lethargic at home and we need to get a bit more drive and endeavor.
"I don't have to give a message to the fans because they've been behind us from day one. I honestly can't believe how good they've been, for a team to be bottom of the league and get the support we are getting is frightening.
The fans have been different class and we need to give them a bit of hope and positivity."
