A first round pick in the 2015 MLS SuperDraft and an undisclosed amount of allocation money will travel in the opposite direction to KC in exchange for the number 9.
Bunbury was drafted fourth overall out of Akron in the 2010 draft by Sporting and scored 21 goals - adding seven assists - in 94 games whilst at Sporting Park.
In August of 2012 the 23-year-old forward suffered a torn ACL in a game against the New York Red Bulls which kept him out of action for 10 months before finally returning last season, when he made 13 appearances, 12 of which were as a substitute.
MLS champions Sporting only play one up front in coach Peter Vermes' preferred 4-3-3 formation and Bunbury was down the list for that lone starting spot, behind Englishman Dom Dwyer and Claudio Bieler, Sporting's designated player.
Bunbury is joining a revolution side that possess a lot of creativity and attacking flair, but last season they lacked a focal point up front and a striker capable of finishing chances players like Diego Fagundez, Kelyn Rowe and Saer Sene created.
Bunbury will be competing for a spot up top with Charlie Davies, Dimitry Imbongo, Jerry Bengtson and this years first round draft pick Patrick Mullins.
