Former 49ers linebacker Reuben Foster, whom Washington claimed off waivers Tuesday, was placed on the Commissioner Exempt list, the league announced.

An NFL spokesman told NBC Sports Bay Area that the league "will continue to review the matter."

The 49ers waived Foster on Monday, two days after he was arrested at the team hotel in Tampa, Fla., following an alleged domestic dispute with on-again-off-again girlfriend Elissa Ennis, who had previously accused him of domestic violence after a February incident at a Los Gatos house they shared.

Washington claimed Foster off waivers, but he'll be ineligible to play for an indefinite period of time, according to league's policy on personal conduct.

“A player who is placed on the Commissioner Exempt List may not practice or attend games," the policy read, "but with the club’s permission he may be present at the club’s facility on a reasonable basis for meetings, individual workouts, therapy and rehabilitation, and other permitted non-football activities.”

Foster was released from Hillsborough County Jail in Tampa on Sunday afternoon after posting $2,000 bail after his arrest for misdemeanor domestic violence. He returned to the Bay Area on a commercial flight early Monday afternoon.
