Washington Redskins linebacker Su’a Cravens has made progress in his recovery from a concussion that knocked him out of the Week 4 win over the Cleveland Browns and forced him to miss Sunday’s win in Baltimore. The rookie remains in the concussion protocol, however, and his coaches say they will not know until later this week about his availability for this weekend’s game.

Cravens sparked a degree of alarm Tuesday when he posted a video on Snapchat in which he said the concussion has affected his vision and prompted the need for him to wear glasses.

“Due to my concussion my eyes have lost the memory to keep track of moving objects, so I have to wear these for the rest of my life,” Cravens, 21, said.

When reached for comment, a team spokesman said the Redskins would not be releasing any statement on the video.

Multiple people within the organization said Cravens had a preexisting need to have his vision corrected. But they didn’t directly confirm or deny that the concussion had further worsened Cravens’s vision and/or intensified the need for glasses.

Concussion-related symptoms can include a temporary inability to track movements, a sensitivity to light, dizziness and headaches.

Cravens must receive multiple evaluations before he received clearance to play. The league’s program requires him to complete a progression of degrees of activity without setbacks or lingering symptoms before an independent doctor clears him to play.

Washington drafted Cravens in the second round of April’s draft. With first-round pick Josh Doctson sidelined indefinitely with tendinitis in his right Achilles’ tendon, Cravens was Washington’s top contributing rookie. His interception in Week 3 sealed the victory over the Giants.
