Patriots sign DL Ellison to roster

The Patriots, who enter the playoffs with a depleted defensive line, have signed free-agent lineman Atiyyah Ellison to their 53-man roster today, the team announced.

Ellison, 29, was a third-round selection of the Panthers in 2005. After spending time in Carolina, Houston, Baltimore, and San Francisco, he made his career debut with the Jaguars in 2009, starting six games. After being released by Jacksonville during final cuts this season, the 6-foot-3, 315 pound Ellison spent Week 7 as an inactive with the Chiefs in their 3-4 defense before being cut on Oct. 27.

The Patriots had an open roster spot after placing rookie defensive end Brandon Deaderick on the reserve/suspended list Monday.

Ellison was one of four linemen the Patriots had in town for workouts on Monday. His addition to the roster is not a surprise given the injury concerns along the defensive line and Deaderick's suspension.

The Patriots also signed defensive lineman Marlon Favorite to the practice squad. Favorite (6-1, 317) is a first-year player who spent his rookie season in 2009 on the practice squads of the Rams, Chiefs, Seahawks and Saints after originally joining the NFL as a rookie free agent with Carolina in 2009 out of Louisiana State. Favorite spent time with Buffalo in the 2010 offseason and then went to training camp with Indianapolis before being released prior to the start of the regular season.
