The striker arrives at the club on a three-month loan deal from Queens Park Rangers and now he can't wait to set about helping Rovers to get back into the Premier League.
"I'm delighted to be playing for Blackburn, it is a great club," said DJ, who came close to signing for Rovers at the end of January.
"I'm delighted it is finally over and sorted. I trained today for the first time, I can't wait.
"Speaking to the gaffer and seeing what his plans were, he really sold it for me, it was an easy choice.
"You only have to come here and see the training ground and Ewood Park, it is a massive club, a club that should be in the Premier League.
"Hopefully with the signings that we've made and if there's a few more to come in then that will only make us stronger and we can push forward to where we want to be, these are exciting times.
