Back in August 2019, Siavii was arrested on suspicion of illegal firearms possession during an altercation that occurred with police in Kansas, according to NBC Sports.
Not long after, a criminal indictment later named Siavii as being part of a methamphetamine drug trafficking conspiracy in Missouri. Siavii was charged alongside eight other co-defendants, the outlet said.
Siavii was transferred to the U.S. Penitentiary at Leavenworth, a medium-security prison, on Dec. 17, The Kansas City Star reported.

Siavii later went on to play for the Dallas Cowboys in 2009, but was cut during preseason in 2010. He then played for the Seattle Seahawks before a spinal cord injury brought his football career to an end in 2011.
