New England has signed DL Louis Leonard, a league source has confirmed.
Leonard is a 6-foot-4, 330 pound lineman who was originally signed as a rookie free agent by the Chargers in 2007. Since then, the 26-year old has played for the Rams, Browns and Panthers.
He began this season in Carolina and played two games before being released; he played in two games of the season for the Panthers in 2009 before being placed on injured reserve with an ankle injury.
In 2008, Leonard played in all 16 games with Cleveland.
He played collegiately at Fresno State, where he was a teammate of Pats' safety James Sanders.
Leonard's arrival could mean that the Patriots do not expect either Mike Wright (concussion), Myron Pryor (back) or Ron Brace (head) to return. Wright suffered a concussion against the Colts and has not been spotted since; Pryor appears to be on his way back to a return. Brace, hurt in the second half against the Bears, is more of an unknown at this point.
The news of Leonard's signing was first reported by Aaron Wilson of the National Football Post.
