Professional career
At the NFL Scouting Combine, Owusu ran a 4.36 time at the 40-yard dash, which tied for the second fastest overall. He wasn't selected in the 2012 NFL Draft, with his concussion against Oregon State and past injury history being a factor. He was eventually signed by the San Francisco 49ers, reuniting him with Jim Harbaugh. He was later waived as part of the 49ers final roster cuts. Owusu later was placed on the San Diego Chargers practice squad. On September 20, 2012 Owusu signed with the Tampa Bay Buccaneers.
