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 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 Dallas Cowboys have exercised their fifth-year option on the contract of Tyron Smith.

Smith’s contract will now run through the 2015 season, fully guaranteeing $10.039 million in the final year, which is equal to the transition tag for offensive linemen in the 2014 season. Smith’s base salary in 2014 is $2.079 million.

Smith was the ninth overall pick in the 2011 draft and was coming off of his first Pro Bowl season.

The Baltimore Ravens have exercised their fifth-year option on Jimmy Smith.

Smith is due just $6.898 million, which is only guaranteed for injury.

Smith has emerged as one of the NFL's better cornerbacks.

Smith had 59 tackles, 16 pass deflections and three forced fumbles in 2013.

The Houston Texans have exercised the fifth-year option on J.J. Watt's contract for the 2015 season.

Watt was the 2012 NFL Defensive Player of the Year.

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.

Chris Johnson has signed with the New York Jets on a two-year deal worth up to $9 million.

The base value of Johnson's deal is $8 million and includes another $1 million in incentives.

"I've always been a big fan of the Jets," Johnson told the team's official website. "There was some thought into this, but just at the end of the day, I was comfortable here. I just felt like it was the right situation."

Johnson averaged just 3.9 yards per carry in 2013.

The New York Giants have agreed upon a one-year deal with Josh Freeman.

Freeman will compete for the No. 2 quarterback job with Curtis Painter and Ryan Nassib.

Eli Manning underwent surgery on his ankle last week.

Freeman, 26, a first-round pick of the Buccaneers in 2009, started 56 games for the team. He enjoyed his best season in 2010, when he started 16 games and threw for 3,451 yards and 25 touchdowns with six interceptions. 

He has struggled since, throwing 43 interceptions over the past four seasons.
