SAN JOSE, Calif. — Police in Northern California say San Francisco 49er Ray McDonald has been arrested on domestic violence charges.

San Jose police Sgt. Heather Randol says the 29-year-old defensive end was taken into custody early Sunday after officers responded to a home in an upscale neighborhood.

McDonald was jailed on felony domestic violence charges.

He has been playing for San Francisco since he was drafted as a third round pick in 2007.

NFL Commissioner Roger Goodell announced tougher penalties last week for players accused of domestic violence.

San Francisco 49ers General Manager Trent Baalke said in a statement Sunday that the team takes “such matters” seriously but is not commenting on the allegations involving McDonald without more information.

Patriots

QUARTERBACK MALLETT TRADED TO TEXANS: In Foxborough, Mass., the New England Patriots traded quarterback Ryan Mallett to the Houston Texans.

The move means second-round draft choice Jimmy Garoppolo will be the backup to two-time MVP Tom Brady. Mallett back up Ryan Fitzpatrick in Houston.

Originally a third-round draft pick from Arkansas, Mallett played four games in three years with the Patriots, completing one pass.

The Patriots picked Garoppolo this year in the second round — the highest coach Bill Belichick has selected a quarterback in New England. In the preseason, Garoppolo was 46 for 79 for 618 yards, five touchdowns and an interception; Mallett was 14 for 26 for 161 yards and a touchdown.

The Texans also released quarterback Case Keenum.

Chiefs

AP SOURCE: CHIEFS’ SMITH AGREES TO 4-YR EXTENSION: In Kansas City, Mo., Chiefs quarterback Alex Smith has agreed to a four-year, $68 million extension that includes $45 million in guaranteed money, a person familiar with the contract told The Associated Press.

The person spoke on condition of anonymity Sunday because the team had not announced the deal, which will keep Smith in Kansas City through the 2018 season.

The Kansas City Star first reported the agreement.

Smith and his representatives had been discussing an extension with the Chiefs for several months, and the veteran quarterback was hopeful a deal would be done before the regular season.

Rams

SAM CLEARS WAIVERS, MEETS WITH FISHER: In St. Louis, Michael Sam showed up for his face-to-face exit meeting with St. Louis Rams coach Jeff Fisher, a few hours after clearing waivers.

Sam arrived at Rams Park via through the media entrance Sunday afternoon still looking right at home clad in a T-shirt, shorts and flip flops. He shook hands with two reporters and accepted well wishes but declined further comment before heading upstairs to see the coach who wasn’t afraid to add the first openly gay player to the roster.

All 21 players released Saturday cleared waivers. Sam’s future was a major topic on Twitter, some of it vitriol, some reasoned.

The Rams appeared unlikely to re-sign Sam to the 10-player practice squad because the defensive line is their strongest unit and they need help elsewhere.

The meeting with Sam meeting was postponed a day so he could attend Missouri’s opening victory over South Dakota State.
