OAKLAND, Calif. (AP) - Oakland Athletics catcher John Jaso is likely to be sidelined another three to four weeks and perhaps for the remainder of the season as he recovers from a lingering concussion.
Jaso flew to Pittsburgh on Monday to be examined by renowned concussion expert Dr. Micky Collins after the catcher experienced nausea, dizziness, headaches and vision problems when he tried to play catch last week.
He took a ball off his mask July 24 at Houston and complained of a headache. Initially, Jaso was placed on the seven-day concussion list the following day, then transferred to the 15-day disabled list on Aug. 8.
Jaso is earning $1.8 million in his first season with the A's. He is batting .271 with three homers and 21 RBIs in 70 games.
