Prior to the 2015 NFL draft Boyko gained interest from several NFL teams and he also participated in the NFL Scouting Combine in Indianapolis, in February 2015. Boyko was ranked as the number one overall prospect in the Canadian Football League Scouting Bureau's September rankings[2] heading into the 2015 CFL draft and later fell to 2nd place in the December rankings.[3] The uncertainty of whether he would stay in the NFL led Boyko to get drafted 14th overall in the 2015 CFL draft by the BC Lions.
