The 21-year-old was struck by a ball in training last week and having been examined by club doctors, they are confident there will be no long-term damage, but have ordered a period of rest.
Caretaker-boss Terry Connor still hopes to have the midfielder available for the last game of the season against Wigan.
"It is two weeks rest for Davis with his eye," Connor told the club's official website.
"He got struck by a ball that ricocheted up into his face. He obviously didn't have time to react, I think it caught him on his retina, or so I'm told.
"He has to go back and get it reviewed and if it hasn't cleared, they'll obviously ask him to rest it more."
Connor concedes there was not much the youngster could do to avoid the injury as the speed of the ball caught him off guard.
He added: "You could see it had no time to react, it hit him flush in the face, he had no chance - he said it caught him in the eye.
"It bloodied his nose but the eyelid or the eye itself was damaged because he didn't have time to react, he didn't have time to close his eyes.
"It was unlucky but that's par for the season we are having."
