A's Jaso still out with concussion, headed back to Oakland for rest

Oakland Athletics catcher John Jaso remains out indefinitely with a concussion after visiting a specialist.

Manager Bob Melvin was hoping Jaso would be cleared to return after seeing Dr. Micky Collins in Pittsburgh on Wednesday. But the doctor wants Jaso to try a different routine.

Melvin said Jaso, sidelined since last month, will return to Oakland and won't resume baseball activities for at least a few days. It's too soon to speculate if he will miss the remainder of the year.

Jaso also sat out most of last season with concussion-like symptoms.

''I'm more worried about the person than I am the baseball player,'' Melvin said.

Jaso is hitting .264 with nine homers and 40 RBI.
