Rovers are pleased to announce that midfielder John O'Sullivan has extended his stay with the club.
The Republic of Ireland Under-21 international has put pen-to-paper on a new contract, which will keep him at Ewood Park until June 2016.
A product of the club's Academy, O'Sullivan has progressed through the ranks to the fringes of the first team, making his Rovers debut away to Birmingham City on the final day of the 2012-13 season.
The 21-year-old ended the 2013-14 campaign on loan at Conference side Southport, where he scored three goals in 21 appearances.
Manager John Coleman secured O'Sullivan's services again at the start of this season, taking him on loan to Accrington Stanley, where the Irishman bagged a brace on his debut, before netting twice more in 13 appearances for the League Two club.
"I'm delighted to stay at Blackburn," said O'Sullivan. "I've been here since I was 15 and it's like home to me.
"Talks have been ongoing for a few weeks, but everything has fallen into place now and I'm glad to be here for another 18 months.
"The plan is to hopefully get out on loan, if possible to a League One team, but even if I do I'll still be thinking about putting thoughts in the manager's mind and pushing for a place here. That's why I've signed this extension, because I think I have a real chance of playing at Blackburn in the future.
"I just need to show the gaffer that I'm good enough and if I do go back out on loan, then hopefully that's what I'll do."
