The San Francisco 49ers may be learning the hard way about why linebacker Reuben Foster had some red flags coming out of college causing him to slip considerably in the 2017 NFL Draft.

Foster has been arrested for the 2nd time in less than a month, according to ESPN’s Nick Wagoner.

Foster was arrested early on Sunday on charges related to domestic violence, threats and possession of an assault weapon, the Los Gatos-Monte Sereno police confirmed to ESPN.

According to the report, officers responded to a disturbance call placed at approximately 9:15 a.m. Sunday at a Los Gatos residence and, upon arrival, spoke to Foster and the alleged victim which ended in Foster’s arrest.

Foster was booked at the Santa Clara County Main Jail, where he was held on $75,000 bail, which was made on Sunday night.

The incident remains under investigation.

“The San Francisco 49ers organization is aware of the report regarding Reuben Foster,” the 49ers said in an official statement. “We take matters of this nature seriously and are gathering all pertinent information.”

Foster was arrested back in January 12th of this year in Tuscaloosa, Alabama, and charged with second-degree marijuana possession, which is considered a Class A misdemeanor in the state.

The latest arrest is just another incident in a long line of troubling ones for the 23-year old linebacker and will certainly make the 49ers think about how to handle Foster’s behavior moving forward.
