Four members of the Washington Redskins were unable to participate in practice on Wednesday afternoon, according to head coach Mike Shanahan during his daily news conference.

Quarterback Kirk Cousins has fallen ill with the flu and sat out practice. In addition, cornerback D.J. Johnson (knee), linebacker London Fletcher (ankle) and guard Kory Lichtensteiger (ankle) were all unable to participate.

Lichtensteiger suffered his injury in Week 17 against the Dallas Cowboys. He has managed to start every game this season and only missed time after hurting his ankle against Dallas. The 27-year-old guard stated on Wednesday that his ankle has improved and he anticipates that he will be available to play against the Seattle Seahawks on Sunday.

Defensive back Cedric Griffin returned to practice on Wednesday for the first time since being suspended by the league for violating the performance enhancing drug policy at the start on December. Shanahan stated that Griffin looked like he hadn't played for some time but was pleased with the quality of his practice.
