The offensive line continues to be upgraded by the Buccaneers. The team has signed left tackle Jabari Levey to a contract. Terms were not disclosed. Levey went to camp with the Oakland Raiders last summer but was one of the final cuts. Levey also played with Berlin of the now defunct NFL Europa this spring and started nine of 10 games. The 6-foot-6, 315-pound Levey played his college ball at South Carolina, where he started his last two seasons at left tackle.
