The Buccaneers signed Owusu to their active roster after they placed backup wide receiver Sammie Stroughter on the injured reserve with an injured foot. The 6'1 Owusu was not drafted after dealing with concussion issues during his senior season at Stanford. Owusu suffered three concussions over a 13 month stretch, causing him to fall off some teams draft boards.
Owusu was medically cleared and got back on the NFL radar with a good showing at the NFL Scouting Combine where he ran a 4.36 40-yard dash. Owusu caught 102 passes during his Stanford career, racking up 1,534 yard while catching 10 touchdowns.
