San Francisco 49ers linebacker Reuben Foster is cooperating with authorities following his second arrest in a month.

Foster has had multiple conversations with team management in person and via phone since his arrest Sunday morning on charges related to domestic violence and possession of an assault rifle, NBC Sports California reported Tuesday.


The 23-year-old Foster's arrest stemmed from an accusation by his girlfriend that he physically dragged her during an argument Sunday morning in Los Gatos, Calif., according to the San Jose Mercury News.

Foster was released from jail on $75,000 bail Sunday night. The extent of the injuries to the victim, who reportedly was involved in a longtime relationship with Foster, was not revealed.

Last month, Foster was arrested in Tuscaloosa, Ala., on a misdemeanor second-degree marijuana possession charge.

The legal issues surrounding Foster could impact how the 49ers approach free agency next month.

Foster is also cooperating with the NFL, according to NBC Sports California. Any player found guilty of domestic violence for the first time could face up to a six-game suspension from the league.

San Francisco cornerback Tramaine Brock was charged in April with felony domestic violence after he was accused of attempting to strangle his girlfriend. He was subsequently cut by the team.

A year ago, Foster was sent home from the NFL Combine in Indianapolis after he had a run-in with a hospital employee. He failed a drug test at the Combine as a result of providing a diluted sample.

On the field in 2017, Foster ranked second on the team in tackles with 72 despite missing five games because of a high ankle sprain and another game with back spasms. He was named the NFL's Defensive Rookie of the Month in November.

Foster capped his college career at Alabama in 2016 by winning the Butkus Award that goes to the nation's top linebacker. He slid to the bottom of the first round as the No. 31 pick in the 2017 NFL Draft because of the character and medical issues (shoulder surgery after his final season with the Crimson Tide).
