Heaney was placed on the 10-day DL on Sunday.

EDGE Analysis

This was strictly procedural as Heaney is slated to miss the entire 2017 season after undergoing Tommy John surgery last summer. He will be transferred to the 60-day DL at some point when the team needs to free up a spot on the 40-man roster.

The Angels have not wavered on their stance of holding Heaney out until the 2018 season at the earliest, the Orange County Register reports.

EDGE Analysis

Heaney underwent Tommy John surgery last July, so a return this season wouldn't have come until the second half of the season at the earliest. He showed promise in his first full season with the Angels back in 2015, posting a 3.49 ERA over 18 starts. Given how shallow the Angels' pitching pool is, it makes sense that they want to take extra precaution with one of their younger arms and hold him out until next season.

Heaney (elbow) will undergo Tommy John surgery, Jeff Fletcher of the Orange County Register reports.

EDGE Analysis

A follow-up exam this week showed that Heaney's elbow has not improved in the two months since he received stem-cell treatment, and thus the decision was made to send him for reconstructive surgery. Considering where we're at in the season and the fact that recovery from Tommy John surgery typically takes more than a calendar year, it seems likely Heaney will remain out through the 2017 campaign.

Heaney underwent an evaluation Monday and found no improvement in his injured elbow, Pedro Moura of the Los Angeles Times reports.

EDGE Analysis

Heaney will be evaluated in two weeks, but it's getting harder and harder to imagine his UCL will heal up enough on its own for him to avoid Tommy John surgery. Even if he is able to return without surgery, this delay pushes his earliest possible return deeper into the season, as he may not be able to return until August in even the best possible case at this point.

Heaney underwent an ultrasound on his UCL and was told it is healing, however he is still unsure of when he will resume throwing, Alden Gonzalez of MLB.com reports.

EDGE Analysis

Heaney landed on the disabled list in early April due to his damaged UCL tendon in his elbow. His progress is encouraging but he'll need progress in order to avoid Tommy John surgery completely.

Heaney is dealing with a damaged UCL in his left elbow but is hoping to avoid Tommy John surgery, Yahoo! Sports reports.

EDGE Analysis

Heaney has made minimal progress since landing on the disabled list in early April with an elbow injury, and the latest report indicates he may be dealing with more than just a minor setback. Heaney figures to continue rehabbing his elbow as long as he can, but if he does not show improvement in the near future, the Angels could decide to send him under the knife.

Heaney will receive a platelet-rich plasma injection into his left elbow, and he will not pitch in a major league game for at least six weeks, the Los Angeles Times' Pedro Moura reports. "I'm not hopeful of anything right now," Heaney said. "At this point, I don't want to get ahead of myself. I'm thinking of today and the next day, not a month, two months, a week, two weeks, whatever."

EDGE Analysis

The 24-year-old southpaw felt tightness in his left forearm during his start on April 5, and has been on the disabled list ever since with what was called a flexor muscle strain. He probably won't throw at all until June, and if all goes well, he would then head out on a rehab assignment. The first week of July is a more realistic return date for Heaney, according to Moura. Given that he could be out two months, owners in shallower formats without the luxury of a DL spot should consider cutting ties with the talented, but unproven lefty.

Heaney is seeking another opinion on his strained forearm, Alden Gonzalez of MLB.com reports.

EDGE Analysis

Heaney had another MRI done one his forearm Monday, which confirmed his diagnosis of a strained left flexor tendon. Unfortunately, it appears his recovery has slowed. He will be checked out by a different doctor. More should be known about his status in the coming days.

Heaney underwent another MRI on Monday, and his diagnosis remains a strained left flexor tendon, Jeff Fletcher of the Orange County Register reports.

EDGE Analysis

Heaney's UCL has so far avoided injury, but the southpaw still isn't throwing much, as he's previously reported tightness in his forearm. With little progress made to date, it's unknown when he'll receive clearance to embark upon a rehab assignment.

Heaney (forearm) is still feeling tightness when playing catch, Pedro Moura of the Los Angeles Times reports.

EDGE Analysis

The left-hander's status has been clouded even further with this news. Manager Mike Scioscia did not so far as to describe it as a setback for Heaney, but did acknowledge that the 24-year-old has hit a "plateau" in his recovery. Team doctors said initially that Heaney's UCL was healthy, with the diagnosis being a flexor muscle strain, but it's always possible the Angels could seek another opinion if Heaney doesn't start making progress again soon.
