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."
