Kevin Williams worked out for the Seattle Seahawks on Monday.

Williams played 11 seasons for the Minnesota Vikings, recording 463 tackles and 60 sacks.

Williams played 746 snaps for Minnesota a season ago at defensive tackle, according to Pro Football Focus data.

The New York Giants have signed Rusty Smith.

Smith was a sixth round pick by the Tennessee Titans in 2010.

Smith is now the fifth quarterback on the Giants' roster, joining Eli Manning, Josh Freeman, Curtis Painter and Ryan Nassib.

The Cleveland Browns will have Vince Young work out with the team during this week's mini camp.

Young last played in the NFL in 2011 with the Philadelphia Eagles. Young has had brief stays with the Buffalo Bills and Green Bay Packers.

Young was a Pro Bowl selection in 2006 and 2009 with the Tennessee Titans.

The Dallas Cowboys have re-signed Anthony Spencer to a deal that could be worth as much as $3.5 million in 2014.

After receiving the franchise tag for the second consecutive year in 2013, Spencer played in only one game before undergoing microfracture surgery to repair articular cartilage damage in his left knee last October.

A 2007 first-round draft pick, Spencer is now the most-tenured member of the defensive line. 

The Carolina Panthers have picked up the fifth-year option on the contract of Cam Newton.

Under the CBA, Newton will be entitled to the average of the league's 10 highest paid quarterbacks in 2015. That estimate comes out at $14.67 million. The Panthers likely won't get to the fifth year of Newton's contract as they remain set on signing him to a long-term deal.

Newton underwent surgery on his left ankle last month. The rehabilitation likely will take him up to the start of training camp in late July.

The Oakland Raiders will cut Terrelle Pryor on Monday if they are unsuccessful in completing a trade by then.

The Raiders acquired Matt Schaub earlier in the offseason.

Pryor is hoping to start in 2014.

The San Francisco 49ers are not expected to exercise the fifth-year option on Aldon Smith for 2015.

Smith was arrested Sunday at Los Angeles International Airport on charges of a false bomb report.

In November, he pleaded not guilty to three felony counts of illegal possession of an assault weapon, stemming from an incident at a party at his home in 2012.

Smith also missed five games this past season while spending time in an alcohol treatment center. 

Smith still finished with 12 sacks despite the five-game absence.

The San Diego Chargers have exercised the fifth-year option on the contract of Corey Liuget.

In 2011, its collective bargaining agreement standardized rookie contracts with a wage scale. All first-round contracts must carry a four-year length with a fifth-year team option. 

Liuget's option is worth $6.969 million instead of $10.633 million, a savings of $3.694 million.

Chad Johnson has signed with the Montreal Alouettes of the CFL.

Johnson last played in the NFL during the 2011 season with the New England Patriots.

The Alouettes have a history of not judging players by their checkered pasts, as evidenced by how they once gave former Nebraska running back Lawrence Phillips a chance on what became a Grey Cup-winning team in Montreal.

Sidney Rice has reached agreement on a one-year deal with the Seattle Seahawks.

Rice spent Wednesday in New Jersey visiting with the New York Jets.

Rice caught 15 passes for 231 yards and three touchdowns in eight games last season.
