The Redskins also announced Tuesday that defensive end Adam Carriker has signed his new deal. Carriker last week agreed to a four-year, $20 million contract with $7 million guaranteed.
Lichtensteiger returns for his third season in Washington. He started the first five games at left guard last season before going on injured reserve with torn ligaments in his right knee.
Carriker also returns for his third season with the Redskins. He had 5½ sacks last season.
