Crittenton appeared in court Wednesday and was sentenced to 23 years in prison.
Prosecutors have said Crittenton was aiming for a man who had robbed him days before the shooting but shot 22-year-old Julian Jones instead.
Crittenton also was arrested in January 2014 on drug charges while he was out on bond.
Crittenton played with Los Angeles, Memphis and Washington. He signed a non-guarantee contract with Charlotte Bobcats in 2010 before being waived.
