He was due an $8.25 million salary this season. In July, he was accused of stomping on a man's head and charged with felony assault for his alleged involvement.
According to TMZ Sports, Smith's next court appearance is scheduled for April 5.
Former Oakland Raiders and San Francisco 49ers linebacker and defensive end Aldon Smith was in a San Francisco courtroom on Monday to enter a not guilty plea. Smith was benched early in his Raiders career and failed to lock down a cornerback position that has since been given to last year's first round rookie, Gareon Conley.

Smith was hit with 4 misdemeanor charges - domestic violence, assault w/ force likely to produce great bodily injury, false imprisonment and vandalism. The Raiders released David Amerson, a starter last season when he was healthy, in February.
A veteran of nine seasons, Smith has also played for the Miami Dolphins and Chiefs and has 14 career interceptions, 102 passes defensed and 424 tackles.
A person familiar with the move said Smith was told Monday that he will be let go before the start of the new league year on Wednesday. TJ Carrie, who started all 16 games in 2017, is set to become a free agent.
