According to Nathan Fenno of the Los Angeles Times, Smith is expected to plead guilty Tuesday to a felony count of assault with great bodily injury. He will be sentenced to one year in jail and five years of probation.
Smith is accused of assaulting his sister's then-boyfriend Christopher Woods in Pasadena last August, causing five fractures to the victim's eye socket. Woods also had to have a metal plate inserted below his right eye.
"He's pleased that [Smith] is admitting guilt, but the sentence is light," Woods' attorney Jonathan Dennis said of the plea bargain.
The 30-year-old appeared in 14 games for the Raiders last season, starting eight.
Smith would have been due $8.25 million in 2018 and possibly $8.75 million in 2019, plus up to $250,000 in workout bonuses, according to Spotrac. However, the four-year contract signed in 2016 included an out this offseason that required no guaranteed money beyond 2017.
The 2009 second-round pick has spent nine years in the NFL, splitting 137 games (123 starts) with the Raiders, Chiefs and Dolphins.
