"Now it's just going to be all about when he's able to move around and play," Melvin said. "So it could be a while. He won't be here today, but he will be here [Wednesday]."
In the meantime, the A's will stick with two catchers -- Josh Phegley and Carson Blair -- and expect Vogt to join them Thursday on their charter to Arlington, where they begin a three-city road swing that also includes stops in Chicago and Houston.
"He moved around quite a bit more today," Melvin said. "He feels like he's getting better."
? Outfielder Sam Fuld is still limited in baseball activity, having been sidelined by back spasms for more than a week, but could potentially be available off the bench as soon as Wednesday, Melvin said.
? Melvin said Chris Bassitt (shoulder) could begin playing catch again by the end of the week, but he's not sure if the right-hander will make another start this season.
"Once he starts playing catch, we'll have a better idea," Melvin said. "We'd love for that to happen, but we're also going to be real careful with him."
