O'Connell (personal) is listed as questionable for Sunday's game against the Saints, Ryan McFadden of ESPN.com reports.
O'Connell wasn't available against the Chargers in Week 2, and he was absent from all three practices during Week 3 prep while attending to a personal matter. He hasn't been ruled out for Sunday's game in New Orleans, but if isn't cleared to play, then Fernando Mendoza would be the lone backup to Kirk Cousins.
