We found out the identity of the other player the Redskins signed to their roster after they released four players and signed three on Tuesday. Offensive tackle Tyler Polumbus was signed to the roster. Here is a look at what the move means.--Polumbus has started games on both the left and the right side at tackle. Sean Locklear was supposed to be the swing tackle but he struggled on the left side while filling in for the injured Trent Williams. He is 26 and if the Redskins like what they see they could attempt to sign him to a deal for next year and beyond.--You dont have to look hard for a Shanahan connection with him. He went undrafted in 2008 but he made the Broncos after Mike Shanahan signed him as a rookie free agent.--In 2009 he started eight games at right tackle for the Broncos, who then were coached by Josh McDaniels. Last year he started seven games for the Seahawks, mostly in place of injured rookie Russell Okung.--The move leaves the Redskins with three reserve tackles on the roster in Locklear, Polumbus, and rookie Willie Smith, and only one backup interior lineman. Jammal Brown has a groin injury and his status for Sunday's game is very much up in he air. Perhaps the thought process was that Smith is not yet ready to fill in if Williams or Locklear should go down during the game. Polumbus gives them veteran depth.
