He was not in the lineup for Oakland's Sunday finale against the Rangers but was deemed available off the bench by manager Bob Melvin.
"He went through a battery of tests this morning and was cleared," Melvin said, "so that's a good thing."
"I feel much better," said Vogt. "Obviously it hurts on touch, but, really, it's just a knot on my head. Nothing I can't play with."
The A's already have one catcher on the seven-day concussion disabled list in John Jaso, who went through several more tests on Saturday.
"Better," Melvin said. "Still not cleared for activity yet, but I think each and every day they have a scale showing he gets better and better every day. I think we're close to baseball activity but still not there yet."
Jaso won't travel with the team to Cincinnati on Monday but there's a chance he can join them in Toronto later in the week.
