Robert Griffin III has agreed to a two-year contract with the Baltimore Ravens.

Griffin will be Lamar Jackson's backup at quarterback after serving as Baltimore's No. 3 last season.

Griffin proved to be an effective quarterback coming off the bench in 2018. 

Griffin was the No. 2 overall pick in the 2012 draft and was named the NFL Offensive Rookie of the Year. 

Haloti Ngata has announced his retirement from the NFL.

Ngata announced his news on Instagram from the top of Mount Kilimanjaro.

Ngata, 35, went to the Pro Bowl five times and won a Super Bowl with the Baltimore Ravens in February 2013.

Ngata also played three seasons for the Detroit Lions and one with the Philadelphia Eagles.

Earl Thomas nearly accepted a one-year guaranteed contract worth $12 million with another $1 million in likely incentives with an undisclosed team.

The undisclosed team was confident an agreement with Thomas would be reached.

But the Baltimore Ravens approached Thomas knowing they had to overpay to break up the other deal, offering a four-year, $55 million deal. Thomas' deal includes $32 million in fully guaranteed money with $22 million coming in the first nine months.

“The Ravens were never in the picture,” Thomas said. “I was shocked. I was blessed.” 

Mark Ingram has agreed to a three-year, $15 million deal with the Baltimore Ravens.

Baltimore was never involved in negotiations with Le'Veon Bell and always had its sights on Ingram.

The Saints' best offer to Ingram was for four years, $17 million with only $5 million guaranteed.

Le'Veon Bell has agreed to sign a four-year, $52.5 million contract with the New York Jets.

The deal contains $35 million in guaranteed money for Bell. The maximum value could hit $61 million with incentives.

Bell sat out the entire 2018 season after he was unable to agree upon a long-term contract with the Pittsburgh Steelers. Bell became a free agent when the Steelers elected not to use a franchise or transition tag on him.

The San Francisco 49ers also made a strong offer for Bell. The Baltimore Ravens, meanwhile, never made an offer.

Bell's average salary per year with the Jets, $13.25 million, would rank him second among running backs in the NFL, behind Todd Gurley's $14.37 million average.

The Steelers offered Bell $70 million last offseason but contained only $17 million in guarantees. Todd Gurley and David Johnson received between $31 million and $45 million in guarantees. Bell called the Steelers' $70 million "Monopoly money." Bell's contract with the Jets doubles his guaranteed money even if it doesn't make up the $14.5 million in lost 2018 money.

The New York Jets have made their best and final offer to Le'Veon Bell.

With Anthony Barr choosing to re-sign with the Vikings, the Jets had some additional cap space to offer Bell.

Bell is believed to be choosing between the Jets and the Baltimore Ravens. Bell has indicated to some friends how much he likes Baltimore. With the Ravens, Bell would play against the Pittsburgh Steelers twice per season.

According to Connor Hughes of The Athletic, the Jets have given Bell a deadline to take their offer.

Le'Veon Bell is expected to make a decision on his free agency on Tuesday.

The New York Jets, Indianapolis Colts, Baltimore Ravens, Green Bay Packers, Houston Texans and Buffalo Bills are believed to be interested in Bell.

According to Pro Football Talk, however, the Colts are not pursuing Bell.

Bell sat out the entire 2018 season.

The Green Bay Packers have agreed to sign Za'Darius Smith and Adrian Amos.

Smith, 26, was the sacks leader for the Baltimore Ravens with a career-best 8.5 last season. Smith underwent sports hernia surgery following the season, but he is expected to be ready for offseason workouts in the spring.

Amos started all 16 games at safety for the Bears.

The Arizona Cardinals have agreed to a one-year, $7 million contract with Terrell Suggs.

Suggs had spent his entire career with the Baltimore Ravens since he was drafted in 2003 out of Arizona State.

Suggs is a seven-time Pro Bowler, most recently in 2017.

Suggs informed the Ravens on Monday that he would be leaving the franchise this offseason.

C.J. Mosley has agreed to a five-year, $85 million contract with the New York Jets. The deal includes $51 million in guaranteed money.

Mosley was the leading tackler for the NFL's top-ranked defense and was the Baltimore Ravens' most high-profile free agent this offseason.

A first-round pick (17th overall) in 2014, Mosley has gone to the Pro Bowl in four of his five NFL seasons.
