Former CFL and NFL running back Lawrence Phillips has been charged with murder in the death of his cellmate at a Central California prison.
Phillips is suspected of killing 37-year-old Damion Soward at Kern Valley State Prison in April. Officials determined Soward was strangled.
The Kern County district attorney's office says the 40-year-old Phillips faces a first-degree murder charge.
Phillips was once one of the top college football players at Nebraska. He played for the St. Louis Rams, Miami Dolphins and San Francisco 49ers during a three-year NFL career.
Phillips ran for 1,022 yards and 13 TDs with Montreal in 2002, helping the Alouettes win the Grey Cup that year. He was released during training camp in '03 for disciplinary reasons before joining the Calgary Stampeders.
Phillips appeared in eight games for Calgary, rushing for 486 yards and a TD before being released after arguing with head coach Jim Barker.
Phillips is serving a sentence of more than 31 years. He was convicted of choking his girlfriend and later of driving his car into three teens after a pickup football game.
KBAK-TV reports Phillips was ordered back to court Sept. 15.
