Bailey was placed on the 7-day concussion injured list Wednesday.
Bailey suffered the concussion during Tuesday's loss to the Cubs when he was involved in a collision at the plate with Jeimer Candelario. He will be eligible to return next week, but as is the case anytime a concussion is involved, it's difficult to project when Bailey might be ready. Blake Sabol and Joey Bart will handle the catching duties for the Giants while Bailey is sidelined.
