Redskins coach Mike Shanahan said that quarterback Robert Griffin III has a “mild sprain to his LCL.” Shanahan said that the sprain to the ligament, which is on the outside of the knee, is a “Grade 1” category, but that there is no other structural damage to the knee. Griffin tore his ACL in the same knee in 2009, but that ligament is fine, Shanahan said.

There is some “mild swelling,” Shanahan said, but Griffin has not been ruled out for Sunday’s game at Cleveland. The hope is that with rehab, the swelling will go down and that Griffin will make a speedy recovery.

Shanahan said Griffin will be monitored “day-by-day.”

Griffin’s father, Robert Griffin Jr., says his son plans to play Sunday against Cleveland. Read the full story here.

Shanahan said “when I looked at it on film, I thought it would be worse than it was.”

Team orthopedic consultant, Dr. James Andrews, was on the Redskins’ sideline and examined Griffin during the game, Shanahan said.

Griffin suffered the injury with 1:56 left in the game as the Redskins were driving downfield to tie the game. On second-and-19, Griffin scrambled around the left end for 13 yards but sustained a serious blow to his right leg while being tackled by Baltimore’s Haloti Ngata.

Griffin had to be helped off the field but returned after one play. He completed two out of four passes, dragging his leg as he made his way downfield, but after the fourth attempt (an incompletion that drew an intentional grounding call), went to the ground and had to be helped off the field again.

Backup QB Kirk Cousins returned to the game and completed a 15-yard pass to Leonard Hankerson to set up third-and-5 from the Baltimore 11, and then completed a touchdown pass to Pierre Garcon with 36 seconds left. Cousins then ran a draw play and scored the two-point conversion to tie the game at 28-28 and force overtime.
