Ray McDonald has been arrested on domestic violence charges.

San Jose police Sgt. Heather Randol confirmed that McDonald, 29, was taken into custody early Sunday after officers responded to a call at 2:48 a.m. PT.

McDonald ranks second among San Francisco 49ers' defensive ends in sacks, snaps and tackles since 2011.

Under the league's newly implemented personal conduct policy, a first domestic-violence offense will result in a six-game ban and a second in a lifetime ban from the NFL.

Alson Smith has been suspended for nine games by the NFL.

Smith will be allowed to remain around the San Francisco 49ers' facility during the suspension, which was very important to the franchise.

Smith already appealed the suspension and lost, making it final.

Smith's suspension is for four games for a violation of substance abuse policy and five games for personal-conduct.

Jerome Simpson has been suspended for three games by the NFL for violating league policy on substances of abuse.

A repeat offender, Simpson will now serve his second suspension in three years. His previous ban resulted from a felony conviction for mailing two pounds of marijuana to his Kentucky home. The latest suspension stems from a DUI arrest last November.

Simpson finished 2013 with 48 receptions and 726 yards.

The one-year suspension for Josh Gordon has been upheld.

Gordon had appealed the suspension in hopes of receiving a reduction.

Gordon will miss all of next year's training camp as well.

Gordon's suspension is a result of a positive marijuana test.

Donald Stephenson has been suspended for four games by the NFL for a violating policy on performance enhancing substances.

Le'Veon Bell and LeGarrette Blount will be charged with marijuana possession following a traffic stop the day the Pittsburgh Steelers flew to Philadelphia for their third preseason game.

Ross Township detective Brian Kohlhepp said traffic officer Sean Stafiej pulled over a Camaro operated by Bell around 1:30 p.m. after Stafiej, who was on a motorcycle, noticed a strong odor of marijuana coming from the vehicle. Stafiej found a 20 gram bag of marijuana inside the car. Bell, Blount and a female passenger all claimed ownership of the marijuana, according to police.

Bell, 22, was taken to a hospital to have blood drawn and is expected to be charged with driving under the influence of marijuana.

Bell and Blount have been close since the latter signed a two-year, $3.85 million contract as an unrestricted free agent with the Steelers in March.

Jerome Simpson could face a three-game suspension due to his drunk driving arrest last season.

Simpson missed the first three games of the 2012 season for violating the NFL's substance abuse policy.

Simpson had 726 yards receiving for the Minnesota Vikings last season, but is behind Greg Jennings and Cordarrelle Patterson on the depth chart.

The NFL is considering changing its policies on domestic violence.

The source confirmed that changes are imminent and expanded on that by saying the NFL is consulting with outside groups to revamp its approach on everything from education, training, assistance and enhanced discipline, which likely would be formally included in the personal conduct policy.

The league plans to move quickly on announcing and implementing the changes, possibly as early as next month.
