John Jaso (concussion) failed to be cleared to play by a doctor Wednesday.

Jaso had a meeting with Dr. Mickey Collins in hopes of being cleared to return, but instead Jaso has been told to cease baseball activities for the time being. Jaso has returned to Oakland, and suddenly his return to the A's during the regular season is up in the air.
Sep 10 - 6:22 PM

John Jaso (concussion) will be examined by Dr. Mickey Collins on Wednesday in hopes of being cleared to return to action.

He would presumably be ready to play on Thursday if all goes well. However, Jaso isn't expected to be used in more than a pinch-hitting role over the final weeks. He can be dropped in fantasy leagues.
Sep 8 - 6:33 PM

John Jaso is expected to return from the concussion disabled list this week.

But Joe Stiglich of CSNBayArea.com suspects that he will be used primarily as a pinch-hitter down the stretch because the A's "don’t want to subject Jaso to further injury behind the plate given the multiple concussions he’s suffered" and have Adam Dunn locked in as the DH against right-handers. Jaso has posted a decent .767 OPS this season, but he can be dumped in most redraft fantasy leagues.
Sep 8 - 10:21 AM

John Jaso (concussion) could be cleared to pinch-hit Sunday.

Jaso has been doing baseball activities the last few days and hasn't had any post-concussion symptoms. While encouraging, Jaso has a history with concussions and the A's can proceed cautiously with him with Adam Dunn aboard. Fantasy owners shouldn't count on much from Jaso in the final weeks.
Sep 7 - 10:14 AM

John Jaso (concussion) ran the bases on Friday for the first time since sustaining his injury.

Jaso still has every intention of returning to the Athletics before the end of the season and has begun to make serious progress towards doing so. With three other capable catchers on the roster, Jaso will be limited to part-time designated hitter duties upon his return.
Sep 5 - 7:00 PM

John Jaso (concussion) took live batting practice Tuesday.

It's the first time he's done so since landing on the disabled list last week with a concussion. The A's will proceed cautiously given Jaso's past concussion issues, likely not using him anywhere but DH for the rest of the season. The 30-year-old is feeling better, though, and thinks he'll be back relatively soon.
Sep 2 - 6:17 PM

John Jaso (concussion) could resume baseball activities this week.

Jaso has missed the last week of action with concussion-related symptoms, but he's starting to feel better. If he is activated at some point in September, the A's are expected to limit him to DH duty given his history of concussions.
Aug 31 - 10:01 AM

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.
Aug 25 - 2:18 PM

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.
Aug 25 - 8:27 AM

Susan Slusser of the San Francisco Chronicle reports that John Jaso has admitted to worsening concussion symptoms over the past two weeks.

It sounds as though Jaso could be headed for another trip to the disabled list, which may have been the driving force behind the A's acquiring Geovany Soto from the Rangers on Sunday.
Aug 24 - 4:53 PM

John Jaso went 2-for-5 and drove home three runs on Sunday, leading the Athletics to a 9-3 victory over the Rangers in Texas.

Jaso singled home a run as part of a five-run uprising in the second inning. He would later add a two-run double in the fifth inning, increasing the A’s advantage to 8-2. He has been one of the better offensive catchers in the American League this season, slashing .286/.361/.471 with eight homers and 38 RBI.
Jul 27 - 10:36 PM

John Jaso (knee) has returned to the Athletics starting lineup for Sunday's game against the Rangers.

Jaso was lifted from Saturday's contest due to irritation in his left knee. He says he's good to go though and will take his place behind the dish on Sunday.
Jul 27 - 4:51 PM

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

The good news is that Jaso said it was more of a cramp than anything else and he expected to be available to play Sunday. "A sharp pain. It kind of scared me, then it gradually went away," Jaso said. "I'm fine now."
Jul 27 - 10:14 AM

John Jaso went 2-for-3 with an RBI in a win over the Blue Jays on Sunday.

Jaso hit an RBI single in the fourth inning, his 26th RBI of the year. The catcher is batting .269/.352/.442 and has proven capable in the leadoff spot for the A's. He's batting .351/.385/.811 in that role this season.
