The Kansas City Chiefs have signed Damien Williams to a two-year, $8.1 million extension. 

Williams, who began the season as a little-used, third-string running back, has emerged as an important player for the Chiefs in the past month since the release of Kareem Hunt.

Williams signed a one-year contract with the Chiefs during the offseason after playing four years as a backup for the Miami Dolphins.

The Los Angeles Rams have signed C.J. Anderson to give the team depth at running back behind Todd Gurley.

Gurley was temporarily sidelined Sunday night against the Philadelphia Eagles and is considered day-to-day because of inflammation in his knee.

Gurley's most trusted backup, Malcolm Brown, was placed on injured reserve after he suffered a clavicle injury in Week 13.

Kelvin Benjamin will sign with the Kansas City Chiefs, according to a source.

The deal is for one year, which means Benjamin will be a free agent this offseason.

The wide receiver was released by the Buffalo Bills earlier this week.

Washington has signed Josh Johnson to back up Mark Sanchez at quarterback.

Johnson last threw a regular season pass in 2011 while with the Tampa Bay Buccaneers.

Washington admitted that they had internally discussed signing Colin Kaepernick before deciding to go in a different direction.
