Marinelli: Calvin Johnson Has ‘Blurry Vision’

Detroit Lions coach Rod Marinelli revealed that Calvin Johnson experienced “blurry vision” after taking a helmet-to-helmet hit towards the end of Sunday’s loss. Johnson said that he’ll “be all right,” but Marinelli wouldn’t clarify whether his second-year receiver suffered a concussion. Johnson, who was listed as questionable on the Week 6 injury report due to a knee problem, could miss more practice time this week.
