San Francisco 49ers linebacker Reuben Foster was arrested and booked into the County of Santa Clara jail on Sunday.

In addition to an allegation of domestic violence, Foster was also booked for suspicion of possessing an assault rifle, according to Robert Salonga, a crime and public safety reporter for Mercury News. Niners Nation learned that Foster is in the process of being released, and his bail will be set at $75,000.

The 49ers released a statement addressing Foster’s situation.

Foster’s arrests could lead to discipline from the NFL, up to and including a suspension. Foster’s cases both stand to be reviewed under the league’s policies on substance abuse and personal conduct.

Both arrests follow a successful rookie season for Foster, in which he was second on the Niners in tackles, with 72 in 10 games. The arrests are added to a list of off-the-field incidents that contributed to Foster’s falling to San Francisco with the No. 31 pick in the 2017 NFL draft.
