There has been no shortage of clubs interested in acquiring the 26 year olds signature, but Rovers had been reported in some parts of the media as favourites to get the striker.
But former Celtic manager Gordon Strachan is the one who has got his man which was revealed by Boyd to the Sunday Mail.
"I'm delighted to finally have my future sorted out," he said
"I've had a few offers to consider and it's been a case of talking to my family about the positives and negatives of each one.
"Middlesbrough have always been very appealing. Strachan has big plans and has made me feel wanted.
"I first met him in January and he impressed me at that meeting.
"Everything has just about been agreed and I will go through my medical today or tomorrow (Monday).
"I don't envisage any problems and I'm looking forward to starting my Boro career."
