Leyton Orient have terminated defender Elliot Omozusi's contract following his conviction last week.
The 22-year-old was jailed for two-and-a-half years on Friday for his part in trying to take revenge on a witness in a gang-related murder trial.
The ex-England Under-17 international and former Leyton Orient player of the year appeared 61 times for the O's.
He had previously played for Fulham before moving to Norwich and then Charlton on loan.
A statement on the club website said: "Following the recent conviction of Elliot Omozusi and subsequent prison sentence of 30 months, the club has reviewed its legal position and has terminated the contract of the defender."
