Kansas City has lost starting center Rodney Hudson for the remainder of the season and Ryan Lilja is expected to step into his spot for the Chiefs. Hudson, a second-round draft pick in 2011, suffered a broken leg in the Chiefs' win over New Orleans on Sunday and was placed on injured reserve. Lilja will slide over from left guard and Jeff Allen will take Lilja's place. "I was comfortable at my position," Lilja told The Kansas City Star. "But on the offensive line you have to be able to play more than one position. It's too bad about Rodney, but it happens all the time so you've got to be ready." The Chiefs also signed veteran offensive linemen Bryan Mattison and Russ Hockstein for insurance. Hochstein has played 10 seasons in the NFL and started 36 games with New England and Denver. Mattison had 13 starts in the past two years with Baltimore and St. Louis.
