Parker (elbow) will avoid having a third Tommy John surgery, but is schedule to have a procedure that will stabilize the medial epicondyle fracture in his arm Tuesday, Susan Slusser of the San Francisco Chronicle reports. A timetable for his return will be clearer after the procedure takes place Tuesday. It's highly unlikely that he'll be back on a big league mound before the end of the 2015 campaign regardless of what is found during the surgery.

Parker will require surgery to repair a fractured bone in his right elbow, MLB.com's Jane Lee reports. It's a devastating setback for Parker, who was starting to close in on a return from his second Tommy John surgery. While it's not known yet if Parker will require the procedure for a third time, doctors will first have to repair the medial epicondyle bone before any further determination is made on the next course of action. The 26-year-old's career remains in serious jeopardy.

Parker (elbow) was moved to the 60-day DL on Saturday, MLB.com's Jane Lee reports. Parker had some tests done on his re-injured elbow Saturday, and it's generally believed that he tore his UCL for the third time. It appears to be a pretty tragic situation for Parker, and from a fantasy perspective it is probably time to cut bait. The transfer to the 60-day DL allows the A's to add newly acquired Edward Mujica to the 40-man roster.

Parker (elbow) is seeing a doctor and undergoing tests Saturday in Nashville, MLB.com's Jane Lee reports. We won't be able to draw any conclusions until the tests are revealed, which likely won't be until Sunday. He left Friday's rehab start with an elbow injury, and considering he was attempting to work his way back from a second Tommy John surgery, optimism should be quite low.

The A's confirmed that Parker exited his rehab start Friday with an elbow injury, Susan Slusser of the San Francisco Chronicle reports. The club added that Parker will be looked at by team doctors. While details regarding Parker's setback remain vague, this clearly is not promising for a pitcher trying to work his way back from Tommy John surgery for a second time.

Parker went down in pain after a pitch and left his rehab start on Friday night, reports Jeff Hem, Nashville Sounds play-by-play reporter. There are no further detail at this point, but this is quite likely horrible news for Parker and the A's. Parker was working his way back from his second Tommy John surgery. There were reports from people at the game that Parker collapsed after the pitch holding his right arm.

Parker (elbow) will throw around 90 pitches in his start with Triple-A Nashville on Friday, MLB.com's Jane Lee reports. This is good news as the A's recently said Parker would need to throw 85-100 pitches in a rehab outing before rejoining the A's rotation. If everything goes well in Friday's outing Parker could be summoned to join the A's in short order. One thing that could prolong this process is the fact that the A's don't really have a pitcher who is struggling in the rotation at the moment, but they will still likely phase Jesse Chavez out when Parker's time comes.

Parker (elbow) will need multiple outings with 85-100 pitches at Triple-A before returning to Oakland, Joe Stiglich of CSN California reports. Parker is slated to throw 75 pitches in his next outing. The Athletics' plan with Parker is to stretch him out to upwards of 100 pitches at Triple-A at least twice before returning to the Oakland.

Parker (elbow) is expected to throw about 75 pitches and cover five innings in his second rehab outing at High-A Stockton on Tuesday, Susan Slusser of the San Francisco Chronicle reports. Parker lasted 3.2 innings in his first turn with Stockton last Thursday, giving up three runs on four hits and no walks. The reports on Parker's velocity were encouraging despite the rather unimpressive pitching line, which could have him on course to join the Athletics within a month.

Parker allowed four hits and three runs over 3.2 innings for Single-A Stockton in his first rehab start coming off his second Tommy John surgery. Parker only struck out one, but it was a good sign that there were reports that he hit 93 miles per hour on his fastball during the start. Assuming no setbacks, Parker is scheduled to return to the A's in late May.
