The 27-year-old striker, who was signed by Gordon Strachan in a £500,000 deal with Aberdeen, has not started a single Championship game this season.
He has made a total of 12 senior appearances for Boro, but is yet to claim his first goal.
He will team up with former Boro skipper Paul Ince at Meadow Lane and is available to make his debut against Tranmere Rovers tomorrow.
