Athletics placed C John Jaso on the 7-day concussion disabled list.
Jaso has been dealing with concussion-like symptoms since early August and the situation got worse this weekend. Geovany Soto was acquired from the Rangers on Sunday to give the A's some needed depth at catcher. Because brain injuries are always unpredictable, there is no exact timetable for Jaso's return.

John Jaso will be placed on the 7-day concussion disabled list.

Jaso began experiencing concussion-like symptoms two weeks ago when he took a foul tip hard off his mask and they got even worse this weekend. "I've just kind of been muscling through the games and trying to power through, but the symptoms have kind of escalated these past few days, and it got to the point where it was a little iffy if I could keep going back there behind the plate and catch," he said Sunday. Oakland has acquired Geovany Soto from the Rangers to help behind the plate.

John Jaso exited Saturday's game versus the Rangers with left knee irritation.

May 24 - 10:28 AM

John Jaso is not in the Athletics' lineup Friday because he's dealing with a little tightness after playing on turf the last few days.

May 23 - 4:06 PM

John Jaso homered in the third and delivered a game-winning double in the 10th as the A's beat the Nationals 4-3 on Saturday.

Jaso thought he might have a second homer in the 10th, but it bounced off the wall in left instead. Fortunately, there were two outs, so Nick Punto was able to run right away and score from first to win the game. It was Jaso's second ever walkoff hit. He has three homers in 80 at-bats this year, matching his total from 207 at-bats last year. He's combined with Derek Norris to give the A's terrific production from the catcher spot so far this year.
