The Green Bay Packers Saturday signed tackle/guard Tyson Walter and placed cornerback Will Blackmon on injured reserve. Ted Thompson, Executive Vice President, General Manager and Director of Football Operations, announced the transactions.

Walter, a 6-foot-4, 300-pound lineman out of Ohio State, entered the NFL as a sixth-round draft choice (179th overall) of the Dallas Cowboys in 2002. In three seasons with the Cowboys (2002-04), he saw action in 40 games with nine starts, eight of those coming during his rookie campaign.

Waived by Dallas at the start of the 2005 season, Walter was out of football until he signed with the Houston Texans on Nov. 18 of that year, but did not see any game action for the Texans. He subsequently signed with the Washington Redskins as an unrestricted free agent on March 24, 2006. Walter played in two games for Washington this season and was inactive for another, before being waived on Oct. 23. The Packers have assigned him No. 70.

Blackmon, selected by the Packers in the fourth round of the 2006 NFL Draft (115th overall), played in four games this season, making 3 special teams stops and 1 pass breakup, and was inactive for the other six contests. He suffered a rib injury Nov. 12 at Minnesota.
