The Kansas City Chiefs have signed Darrelle Revis.

Revis had been a free agent this season.

"The reason for me returning is the fire I have, the fuel I have to continue to play this game at a high level,'' Revis said. "My role is to help win. Whatever is best for the team, whether my position is playing a few downs or playing in the slot, wherever Coach wants to play me and feels he can utilize me to help win.''

Marcus Peters and Steven Nelson have been the starting cornerbacks, but the Chiefs have struggled to find any consistency from their third cornerbacks.

The Arizona Cardinals have announced a one-year contract extension with Larry Fitzgerald.

Fitzgerald's contract previously had a voidable year in 2018 for cap purposes, but the new agreement assures the future Hall of Famer will play next season.

He currently ranks sixth in the NFL's all-time receiving list with 15,066 yards. Barring injury, he should finish the season third, behind only Jerry Rice and Terrell Owens.

The Philadelphia Eagles have signed Tim Jernigan to a four-year extension.

The $48 million deal includes $26 million fully guaranteed, according to a source.

The Eagles acquired the defensive tackle and a 2017 third-round pick from the Baltimore Ravens on April 4 for in exchange for Philly's third-round pick, which was higher in the round.
