Weaver (elbow) will throw a bullpen session Friday, Richard Morin of the Arizona Republic reports.

EDGE Analysis

If all goes well for Weaver on Friday, manager Torey Lovullo said the next step for the right-hander is throwing to live batters. Weaver has been on the injured list since late May.

Weaver (elbow) threw a 20-pitch bullpen session Tuesday, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Weaver came out of the session feeling good, according to the team. The right-hander threw only fastballs during the session, his second such bullpen since suffering the injury in May.

Weaver (elbow) was transferred to the 60-day injured list Friday.

EDGE Analysis

This move is simply procedural, as Weaver has already been on the shelf for 60 days. The right-hander is set to receive a follow-up MRI this week, after which a more concrete timetable for his return will hopefully emerge. To replace Weaver on the 40-man roster, Yasmany Tomas had his contract selected from Triple-A Reno.

Weaver (elbow) will undergo another MRI next week to assess his recovery, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Weaver has started throwing and is playing catch out to 75 feet. Next week's MRI should give a clearer indication of his potential return to the rotation. The right-hander landed on the injured list in late May and will likely need at least two rehab starts.

Weaver (elbow) has begun a throwing program, Nick Piecoro of the Arizona Republic reports.

EDGE Analysis

Weaver, who is throwing out to 60 feet, is in the early stages of his rehab. He's been sidelined since the end of May with a mild flexor pronator strain and a minor UCL sprain. The Diamondbacks have not provided a timetable, but with Weaver just now starting to throw, early-to-mid August would be the earliest.

A follow-up MRI on Weaver's elbow showed improvement, Steve Gilbert of MLB.com reports.

EDGE Analysis

Weaver has been sidelined since the end of May with a mild flexor pronator strain and a minor UCL sprain. While the right-hander has shown improvement, it remains to be seen when he'll be able to resume a throwing program, leaving Weaver without a timetable for his return.

Weaver has been diagnosed with a mild flexor pronator strain and a minor UCL sprain, and he'll be "treated conservatively," Richard Morin of The Arizona Republic reports.

EDGE Analysis

The fact that Weaver has opted for conservative treatment means he won't be going under the knife, though the Diamondbacks also haven't released a timetable for when he could resume throwing. The team should reveal more information once the right-hander is cleared to begin a throwing program.

Weaver has been diagnosed with a right forearm strain and will seek a second opinion, Nick Piecoro of The Arizona Republic reports.

EDGE Analysis

Weaver was placed on the 10-day injured list Monday after leaving Sunday's start with a forearm injury. It remains to be seen how much time he'll miss while on the shelf, but he's headed for a second opinion to determine the next step in his recovery process. Manager Torey Lovullo is "very hopeful" that Weaver will be able to avoid a surgical procedure of any sort, per Piecoro.

Weaver (forearm) was placed on the injured list Monday, Nick Piecoro of The Arizona Republic reports.

EDGE Analysis

Weaver exited Sunday's start in the sixth inning after stating he felt something "a little abnormal" after throwing a changeup. It's unclear how long he'll remain sidelined, though he is undergoing an MRI on Monday. Any absence will be unfortunate for the 25-year-old, as he had been experiencing a resurgent campaign by posting a 3.03 ERA and 1.11 WHIP across 62.1 innings.

Weaver (4-3) earned the win in Sunday's 6-2 win over the Giants before leaving the game with a forearm injury.

EDGE Analysis

Weaver, who is the midst of a breakout season, told Nick Piecoro of the Arizona Republic that something he felt was "a little abnormal" after throwing a changeup in the sixth inning and decided to leave the game with Arizona up by five runs. He and the Diamondbacks are downplaying the injury with manager Torey Lovullo making no assurances an MRI is even needed. Still, the team will investigate the injury and more details should follow. The Diamondbacks do not have the luxury of getting by with four starters for a stretch and will need to make a decision before Weaver's next scheduled start Friday at home against the Mets.
