The Falcons have signed Julio Jones to a five-year contract extension, the team announced Saturday before its preseason game against the Dolphins.

Jones, 26, will receive $71.25 million over the life of the deal, with $47.5 million guaranteed, sources told ESPN's Chris Mortensen.

The Oakland Raiders have signed Taylor Mays.

Mays was released recently by the Detroit Lions.

Mays is entering his sixth NFL season, following stops with the San Francisco 49ers and Cincinnati Bengals.

Mays played collegiately at USC from 2006-09 while Raiders defensive coordinator Ken Norton, Jr. coached on the defensive side of the ball and eventually served as the assistant head coach defense/linebackers in 2009, Mays’ final collegiate season. 

Rex Grossman has signed with the Atlanta Falcons and will compete for their backup quarterback job.

Grossman joins T.J. Yates and Sean Renfree in the competition for the No. 2 QB role behind Matt Ryan.

Grossman hasn't thrown an NFL pass since 2011.

The Steelers have signed free-agent quarterback Michael Vick to a one-year deal, the team announced Tuesday.

Vick met with the Steelers earlier in the day, sources told ESPN's Adam Schefter and Josina Anderson, as the team was in the market for a backup to Ben Roethlisberger after Bruce Gradkowski dislocated a finger in his left hand during last week's preseason game against the Packers.

Evan Mathis has agreed to sign with the Denver Broncos on a one-year deal worth $2.5 million with a chance to each $4 million total with incentives. Mathis had protested his $5.5 million salary with the Philadelphia Eagles.

Mathis was released by the Philadelphia Eagles earlier this offseason.

Mathis has multiple Pro Bowl appearances at guard.

Mychal Kendricks and the Philadelphia Eagles have agreed upon a four-year extension worth $29 million.

The deal contains $16 million in guaranteed money for Kendricks.

Kendricks was a second round pick at middle linebacker out of California in 2012.

Reggie Wayne and the New England Patriots have agreed upon a one-year deal.

Wayne was a free agent after spending his entire career with the Indianapolis Colts.

Wayne also received interest from the Green Bay Packers.

The Tampa Bay Buccaneers have agreed to sign Gosder Cherilus to a two-year deal worth as much as $7 million.

The Buccaneers needed to make a move at tackle following Demar Dotson's injury.

Cherilus, who was the Indianapolis Colts' starter at right tackle the past two seasons, was released by the team the past month.

Chris Johnson has agreed upon a one-year deal with the Arizona Cardinals.

Johnson spent last season with the New York Jets.

During the offseason, Johnson was shot in a drive-by that killed the driver of his vehicle.

Philip Rivers and the San Diego Chargers have agreed upon a four-year extension.

Tom Telesco said he wanted to make sure that Rivers retired with the Chargers.

The new deal worth $83.25 million with $65 million guaranteed gives Rivers the highest guaranteed money of any player under a current contract.

The Chargers potentially relocating to Los Angeles reportedly had been a source of heartburn for Rivers, who wasn’t keen on moving his family a couple of hours north.
