The Seattle Seahawks have signed Cliff Avril to a four-year extension worth as much as $28.5 million with $16 million in guaranteed money.

Avril signed with Seattle two years ago after turning down a three-year, $30 million offer from the Detroit Lions.

Avril has been a productive pass rusher for the Seahawks.

The Seattle Seahawks have signed K.J. Wright to a four-year extension worth $27 million.

"In the offseason, we identified K.J. as one of our core players moving forward and aimed to keep him as a part of the Seahawks family for a long time," general manager John Schneider said in a statement. "The timing of this signing gives us the ability to keep as many of our core players together as we possibly can. Since Day One, K.J. has been a true professional in his daily approach and we are excited for K.J., his family and the 12s to keep him in the organization."

Wright has started 54 of 58 games over four years, emerging as one of the NFL's best coverage linebackers. He has also exhibited impressive closing speed in the run game and as a situational blitzer.

The Denver Broncos and Chris Harris have agreed upon a five-year, $42.5 million contract extension.

Harris will collect a $10 million signing bonus and $24 million in guarantees, per Rapoport. Among all NFL cornerbacks, his contract ranks 12th in annual average.

Harris has held opposing quarterbacks to a 46.9 passer rating on throws in his direction, per Pro Football Focus, ranking with Richard Sherman and Vontae Davis among the league leaders. He hasn't surrendered more than 50 yards receiving or a single touchdown in the last calendar year.
