Lichtensteiger sustained the injury during Sunday night's Week 17 meeting with the Dallas Cowboys. The 27-year-old was forced to leave the game in the third quarter and was replaced by rookie Josh LeRibeus. Lichtensteiger started all 16 games this season.
On Monday morning, he stated that he hopes to be ready for the team's Wild Card playoff game against the Seattle Seahawks this Sunday.
Shanahan also stated that cornerback Cedric Griffin will return to practice this week. Griffin was suspended for four games on Dec. 4 for violating the league's performance enhancing drugs policy. His status for Sunday's game will be evaluated at the end of the week.
In addition, Shanahan acknowledged that quarterback Robert Griffin III might be slightly bothered by the brace on his knee. While he admits that the quarterback is not fully recovered yet, he does not believe that Griffin is hiding the severity of his injury or at risk of re-injuring the area.
