Alex Boone is expected to report to the San Francisco 49ers by the end of Monday to end his holdout.

Boone will sign a new two-year deal to replace his old contract with an increase in salary and incentives.

The 49ers also will not be able to use their franchise tag on Boone once the new contract has expired, sources said.

Boone originally was scheduled to make up to $4 million over the next two seasons under his previous deal, sources said.

The Houston Texans have traded for Ryan Mallett from the New England Patriots, sending a conditional sixth or seventh round pick in 2015.

The Texans are entering the 2014 season with Ryan Fitzpatrick as their starter.

To make room for Mallett on their roster, the Texans will waive quarterback Case Keenum, a source told ESPN.

Mallett was passed on the Patriots' depth chart this summer by rookie Jimmy Garoppolo, a second-round pick who impressed throughout training camp and the preseason.

Michael Sam went unclaimed on waivers after his release by the St. Louis Rams on Saturday.

Sam is now to sign with an NFL team's practice squad.

Sam arrived at Rams Park on Sunday for a face-to-face exit meeting with Jeff Fisher. The meeting was postponed a day so Sam could attend Missouri's opening victory over South Dakota State.

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.

Alex Smith has signed a four-year contract extension with the Kansas City Chiefs worth $17 million per season.

Smith's deal includes $45 million in guaranteed money.

The Chiefs dealt for Smith from the San Francisco 49ers for two second round picks.

“It was a priority of ours to get this deal done and keep Alex in a Chiefs uniform long-term,” general manager John Dorsey said in a statement. “Alex is a proven leader on and off the field. He is a special individual with a lot of ability, and we are fortunate to have him here.”

Nate Burleson has been cut by the Cleveland Browns.

Burleson has been dealing with a lingering hamstring issue and played in just one preseason game.

Burleson had 461 yards and one touchdown last season for the Detroit Lions.

James Harrison has announced his retirement from the NFL.

Harrison spent 10 seasons with the Pittsburgh Steelers and one last year with the Cincinnati Bengals.

"I have made the difficult decision to retire as of today," Harrison's statement said. "My love for my family and the need to be there for them outweighs my desire to play the game. I have missed too many experiences with them because I devoted SO much time to my career.

"My love for the game isn't strong enough to make up for missing one more birthday or first day of school."

The 36-year-old Harrison entered the league in 2002 as an undrafted free agent out of Akron. 

The Cincinnati Bengals have signed Vontaze Burfict to a contract extension through 2017.

Burfict led the NFL in tackles in 2013 and was eligible for a new deal because he wasn't drafted.

“Vontaze is a special talent; he has shown us that from his first day here,” Marvin Lewis said. “He is a load physically and he’s extremely competitive, but what really makes him stand out is the instinct and feel he has for the game. It’s something born in him, you can’t coach a player to naturally react the way he does in all situations. This signing is a great move for the future of our defense.”

“It’s unusual to sign a player this early in his career to a contract extension, but Vontaze is a player who merits this,” executive vice president Katie Blackburn said. “He has proven to be an exceptional find for us, and we are happy to reward him now for his accomplishments. It’s good for him and good for our team.”

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.

Sammy Watkins left in the first quarter of the Buffalo Bills' preseason finale on Thursday when he reinjured his ribs.
