The Kansas City Chiefs and Eric Berry have agreed upon a six-year, $78 million deal.

The contract will make Berry the NFL's highest paid safety.

The deal includes $40 million guaranteed and a $20 million signing bonus.

The Kansas City Chiefs are finalizing a five-year, $41.25 million extension with Laurent Duvernay-Tardif.

A sixth-round pick in the 2014 NFL Draft, Duvernay-Tardif has started 30 games over the past two years after essentially redshirting as a rookie.

Duvernay-Tardif has become one of the NFL's best run blockers at right guard.

Duvernay-Tardif is also a medical student at McGill University in Montreal.

Antonio Brown has agreed upon a four-year, $68 million deal with the Pittsburgh Steelers. Brown is now signed through the 2021 season.

The deal averages $18.5 million over the next three seasons and $17 million over the next four.

The Steelers had promised to rework Brown's contract this offseason. They restructured his contract last August, advancing $4 million of his 2017 salary into his base salary for 2016.

Brown had one season remaining on the five-year, $42 million deal he signed with Pittsburgh in 2012.

The Kansas City Chiefs have signed C.J. Spiller.

The Chiefs are Spiller's fourth team in the last five months.

Spiller was a first-round pick in 2010.

The Miami Dolphins and Cameron Wake have agreed upon a two-year extension worth $19 million with $11 million guaranteed.

Wake overcame adversity last year by bouncing back from a season-ending Achilles injury in 2015 to lead the Dolphins with 11.5 sacks. He made his fifth career Pro Bowl as a result and is one of Miami's emotional leaders.

Miami cleared cap room earlier this week with the release of former defensive linemen Mario Williams and Earl Mitchell.
