Bosa questionable; 2 other D-linemen out

Niners EDGE Nick Bosa (groin) is questionable for Sunday's game against the Falcons. DL Arik Armstead (foot, ankle) and DT Javon Kinlaw (knee) are out. Bosa missed the week's 1st 2 practices after leaving last week's win over the Panthers early. He returned for a limited Friday workout. We'll check his status Sunday.
