Fiers (hip) hasn't experienced any setbacks while he builds his arm up for the regular season according to Athletics head trainer Nick Paparesta, Martin Gallegos of MLB.com reports.

EDGE Analysis

Paparesta gave his update regarding Fiers on Thursday, noting the veteran right-hander "was able to get his innings in on Monday" during a simulated game at the alternate training site and adding he'd be repeating that process again soon. The Athletics remain encouraged by Fiers' setback-free rehabilitation process thus far, but he'll likely require at least a couple of more outings before being deemed ready for regular-season action.

Fiers (hip), who pitched in a simulated game Monday at the Athletics' alternate training site, is likely to do so at least two more times before a possible late-April regular-season debut, Jessica Kleinschmidt of NBC Sports Bay Area reports.

EDGE Analysis

With the minor-league season not beginning until early May, the only way to get a rehabbing player such as Fiers some game action is through sim games at the alternate training site. As such, the veteran right-hander will continue building his arm up that way after missing the entire Cactus League slate. Manager Bob Melvin offered late April as the goal for Fiers' 2021 debut, but he could be pushed back further if there are any setbacks along the way.

Fiers (hip) will throw three innings against the Giants' Triple-A Sacramento players at the Athletics' alternate training site Monday, the Associated Press reports.

EDGE Analysis

It's a relatively notable step for the veteran right-hander in his recovery, considering he never got an opportunity to pitch in a Cactus League game this spring. Getting Fiers a taste of game action -- albeit against minor-league bats -- is presumably a good litmus test at this point with respect to his ongoing preparation for his eventual 2021 debut.

Fiers (hip) is likely to conduct his next throwing session at the Athletics' alternate training site in Stockton soon, the Associated Press reports.

EDGE Analysis

Fiers threw a simulated game Wednesday as he continues to prepare for what he and the Athletics hope is a late-April season debut. The veteran right-hander never had an opportunity to pitch during Cactus League play, so he presumably has plenty of work to do in building up his arm for a normal workload.

Fiers (hip) is scheduled to pitch two innings in a simulated game Wednesday, Alex Coffey of The Athletic reports.

EDGE Analysis

The sim game marks the next step in the recovery process for Fiers, who was cleared to resume mound work last week after being diagnosed with hip inflammation earlier this month. Fiers will begin the season on the 10-day injured list, but if he advances through his throwing progression without any setbacks to his hip, he could rejoin Oakland's rotation at some point in April. The Athletics are expected to turn to Daulton Jefferies, A.J. Puk or Cole Irvin to serve as their fifth starter while Fiers is out.

Fiers (hip) was placed on the 10-day injured list Friday, Martin Gallegos of MLB.com reports.

EDGE Analysis

Fiers hasn't even faced hitters this spring, as he initially dealt with what was described as a "minor" back issue that ultimately progressed to hip discomfort. The right-hander also experienced back tightness while playing catch a week ago, and the Athletics finally decided a move to the injured list for the normally durable Fiers was the best course of action. A.J. Puk, Daulton Jefferies and Cole Irvin are all candidates to fill Fiers' spot in the rotation to open the season, with whoever secures the job presumably set for multiple starts given that Matt Kawahara of the San Francisco Chronicle reports the veteran will miss at least the first three regular-season series.

Fiers (hip) threw a bullpen session Friday, Shayna Rubin of The San Jose Mercury News reports.

EDGE Analysis

Fiers was shut down in mid-March with hip inflammation and received an injection at the start of last week. He's been able to play catch for over a week and has now advanced to bullpen sessions, which is certainly good progress, but he won't have time to get up to speed by Opening Day and is expected to open the year on the injured list.

Fiers (hip) will play catch Thursday, Alex Coffey of The Athletic reports.

EDGE Analysis

Fiers received an injection Monday to address inflammation in his hip. He's yet to make his Cactus League debut this spring, so it looks as though he may not have time to get up to speed by Opening Day. However, assuming his recovery advances without setbacks, he may not miss too many turns in the rotation.

Athletics manager Bob Melvin said that Fiers will receive an injection Monday after a recent MRI revealed inflammation in his hip, Matt Kawahara of the San Francisco Chronicle reports. He's expected to be shut down a few days while he waits for the shot to take effect.

EDGE Analysis

Fiers has yet to make an appearance during the Athletics' Cactus League slate due to what was originally termed as a back issue before the MRI revealed a different injury. According to Kawahara, Melvin labeled Fiers as "a little bit of a long shot" for Opening Day, given that the right-hander is far behind the Athletics' other rotation members in his build-up program for the start of the season. Assuming Fiers opens the season on the injured list, the Athletics could turn to A.J. Puk or Daulton Jefferies to serve as their fifth starter.

Fiers (back) has been shut down and will get an MRI on Sunday, Alex Coffey of The Athletic reports.

EDGE Analysis

Fiers has yet to get into game action this spring due to what the Athletics originally called a minor back issue. He suffered a setback Friday, and the team is now worried that he might actually be dealing with a hip problem. He hasn't been ruled out for Opening Day yet, but it's very possible he won't be ready if the MRI reveals anything more than a minor issue. Cole Irvin could potentially be next in line for starts if Fiers misses time, as A.J. Puk is expected to open the year in the bullpen.
