The Miami Dolphins have exercised the fifth-year option on the contract of Mike Pouncey.

Pouncey was a Pro Bowl center during the 2013 NFL season.

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.

Chip Kelly has received the support of Philadelphia Eagles' owner Jeffrey Lurie in the decision to release DeSean Jackson.

The Eagles have denied the decision as being anything more than a "football decision."

"It was really a football decision," Lurie told the Philadelphia Inquirer. "Chip and his people were incredibly clear that for us to get better we need to take a step back and reconfigure the wide receiver position. I think common to a lot of really smart coaches, he knows exactly what he wants at every position. And for Chip on offense, it just wasn't a good fit. It just was not a good fit with what he asks wide receivers to do."

Earl Thomas has agreed to a four-year, $40 million extension with the Seattle Seahawks.

Thomas' deal makes him the highest paid defensive back on a true multi-year deal.

Thomas will become a free agent when he's 29 if this deal is played out until the end.

Thomas was due $4.725 million in the final year of his old deal.

The Detroit Lions are meeting with Marqise Lee, the seventh team to meet with the USC receiver.

The Lions own the highest pick at No. 10 that Lee has met with.

Lee also has visited with the Baltimore Ravens (17th pick), New York Jets (18th pick), Miami Dolphins (19th pick), New Orleans Saints (27th pick), Carolina Panthers (28th pick) and New England Patriots (29th pick).

The Atlanta Falcons appear increasingly less likely to remain at No. 6 in the 2014 NFL Draft.

The Falcons are considering the possibility of moving all the way up to No. 1 to draft Jadeveon Clowney.

Talks between the Falcons and Houston Texans have not begun, however.

The Falcons could also consider moving down since the top-10 is considered strong.

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 Seattle Seahawks have hired Jeff Ireland to serve as a consultant ahead of next month's draft.

Ireland had been general manager of the Miami Dolphins from 2008 until January.

Ireland and the Seahawks will discuss a full-time position when the draft is over.

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.
