Weaver (shoulder) is awaiting a second opinion, Zach Buchanan of The Athletic reports.

EDGE Analysis

It's hard to say when Weaver will be able to return, but there should be more clarification when the results of this second opinion are known. His injury is currently being labeled as shoulder discomfort.

Weaver (shoulder) was placed on the injured list Tuesday.

EDGE Analysis

Weaver hoped to not miss a turn in the rotation after exiting his Sunday start with shoulder discomfort, but the Diamondbacks evidently had other ideas. His optimism suggests he isn't in for a long absence, though the team has yet to provide a timeline for his return. Corbin Martin was recalled in a corresponding move and will start Tuesday against the Dodgers.

The Diamondbacks plan to place Weaver (shoulder) on the 10-day injured list Tuesday, John Gambadoro of Arizona Sports 98.7 FM reports.

EDGE Analysis

After exiting his start Sunday against the Nationals with right shoulder discomfort, Weaver was optimistic that he would avoid a stint on the IL, but the Diamondbacks apparently didn't agree with the 27-year-old's assessment of his health. With Weaver due to miss at least one turn through the rotation, the Diamondbacks are expected to call up Corbin Martin from Triple-A Reno to make a spot start at some point during their ongoing four-game series with the Dodgers.

Weaver (shoulder) said after his early exit in Sunday's 3-0 loss to the Nationals that he's "pretty confident" he'll be available for his next turn through the rotation Friday in Colorado, Zach Buchanan of The Athletic reports.

EDGE Analysis

Weaver covered four scoreless frames before he was removed with an injury the Diamondbacks labeled as right shoulder discomfort. According to the pitcher, he believes that the discomfort was caused by poor mechanics, and he suspects that he'll be good to go if he makes a proper tweak to his delivery. Weaver has covered 10.1 scoreless frames between his last two outings, lowering his season ERA from 6.07 to 4.50 in the process.

Weaver left Sunday's game against the Nationals with right shoulder discomfort.

EDGE Analysis

Weaver allowed a hit and two walks while striking out three in four scoreless innings prior to his removal from Sunday's game. It's not yet clear whether the injury will impact his availability for his next outing. Weaver tentatively lines up to make his next start on the road Friday against Colorado.

Weaver (2-3) allowed four hits over 6.1 scoreless innings Monday, striking out six and earning a win over Miami.

EDGE Analysis

Weaver had been stuck in a brutal stretch entering Monday's game, allowing 17 runs in as many innings while going 0-3 over his last four starts. He gave up two extra-base hits in the shutout appearance but was never in too much danger. The 27-year-old right-hander lowered his season ERA to 5.00 through 36 innings. He's projected to take the mound this weekend at home against Washington.

Weaver will remain in the rotation and is expected to start Monday at home against the Marlins, Steve Gilbert of MLB.com reports.

EDGE Analysis

Arizona manager Torey Lovullo had discussions on the best path forward for Weaver, who has a 9.00 ERA and allowed 25 hits and 10 walks over the last four starts (17 innings). This doesn't mean he's out of the woods yet. The Diamondbacks have Jon Duplantier, who is currently on the taxi squad while the team is on the road, and he's stretched out 70 pitches.

Manager Torey Lovullo and his staff are having discussions about the next steps for Weaver after a rough outing Wednesday, Steve Gilbert of MLB.com reports. "We're right in the middle of that conversation," Lovullo said. "We're trying to make the best decisions moving forward to help this team win baseball games every single night."

EDGE Analysis

Weaver allowed six runs over four innings Wednesday, pumping his ERA up to 6.07 after six starts. Following the game, the manager was not ready to give up on the right-hander, which is prudent given that Arizona is down a couple of other starters already in Taylor Widener (groin) and Merrill Kelly (undisclosed). Weaver lines up to start Monday at home against the Marlins, the team he faced Wednesday.

Weaver (1-3) allowed six runs on six hits and two walks with six strikeouts in four innings in a loss to Miami on Wednesday.

EDGE Analysis

Weaver struggled early on, as he allowed a pair of runs in the first inning. In the second, he gave up an RBI triple to Miguel Rojas and a three-run home run to Adam Duvall. It's been a difficult start to the season for Weaver, who owns a 6.07 ERA, 1.38 WHIP and 29:11 K:BB across 29.2 innings. He's also given up six home runs across six starts, which likely plays a big part in his poor numbers. The right-hander is projected for a rematch with Miami next week.

Weaver allowed three runs on five hits while walking three and striking out four over four innings in Thursday's win over the Rockies.

EDGE Analysis

The righty had command issues all evening which consequently was the reason he was pulled after four innings. The 27-year-old threw 54 of his 85 pitches for strikes and had multiple long innings against the Rockies lineup. Weaver now has a abysmal 4.91 ERA on the year.
