Ladarius Green, San Diego Chargers, concussion, (Q): Green made a surprise appearance in practice Friday, running routes and catching passes just two days after being diagnosed with a concussion. This would suggest his symptoms had cleared entirely within 24 hours and he was moving through physical activity testing. He would still need to be cleared for contact and cleared by all physicians to return to play in a game before being eligible to suit up Sunday, hence the questionable tag.
