Zimmermann's (elbow) rehab start with Triple-A Toledo has been pushed back due to left glute tightness, Cody Stavenhagen of The Athletic reports.

EDGE Analysis

Zimmermann, who has been on the shelf since the end of April with a UCL sprain in his right elbow, was originally scheduled to begin a minor-league rehab assignment with the Mud Hens on Wednesday, but that will have to wait after the veteran right-hander felt something in his glute. At this point, it's unclear how long this injury will set Zimmermann back. An updated timetable for his return should emerge once he's able to resume his rehab assignment.

Zimmermann (elbow) will make a rehab start at High-A Lakeland on Wednesday, Jason Beck of MLB.com reports.

EDGE Analysis

Zimmermann completed a 40-pitch simulated game Friday, clearing the way for the start of a minor-league rehab stint. The 33-year-old will likely require an additional rehab start before potentially making his way back to the starting rotation.

Zimmermann (elbow) is expected to pitch a simulated game Friday, Chris McCosky of The Detroit News reports.

EDGE Analysis

Zimmermann has been dealing with a sprained UCL since late April. He's behind his initial 3-to-4 week timeline and appears on track to return to action in mid-June.

Manager Ron Gardenhire said Thursday that Zimmermann is tending to a muscle strain in addition to his sprained right elbow and is "probably a month" away from returning from the 10-day injured list, Cody Stavenhagen of The Athletic reports.

EDGE Analysis

When Zimmermann was shut down with a UCL sprain in late April, it was estimated that he would be sidelined for 3-to-4 weeks. Gardenhire's comments suggest Zimmermann's setback will result in the 32-year-old's recovery timeline being pushed back another four weeks, putting him in line for a mid-June return at the earliest. The Tigers were already lacking in quality rotation depth heading into 2019, and injuries to Zimmermann, Michael Fulmer (elbow), Matt Moore (knee) and Tyson Ross (elbow) have only compounded matters.

Zimmermann (elbow) is still feeling discomfort when throwing, Evan Woodbery of MLive.com reports.

EDGE Analysis

Zimmermann doesn't appear to have suffered any setbacks, he's just not progressed as quickly as expected from the sprained UCL he suffered in late April. He had initially be tracking towards a return in late May but now appears to be behind that timeline.

Zimmermann (elbow) was cleared to play catch Sunday, Chris McCosky of The Detroit News reports.

EDGE Analysis

Zimmermann was only able to complete some light tosses off flat ground in what marked his first activity since landing on the 10-day injured list last week with a UCL sprain in his right elbow. The Tigers haven't outlined a formal timeline for Zimmermann's return from the IL, but it's expected he'll be sidelined for a minimum of 3-to-4 weeks while working through the elbow issue. Ryan Carpenter is the leading candidate to receive a callup from Triple-A Toledo to enter the rotation when the Tigers first require a fifth starter during their May 11 doubleheader in Minnesota.

Zimmermann (elbow) has been shut down from throwing for one week, and in a best-case scenario, he could return from the injured list in 3-to-4 weeks, Anthony Fenech of the Detroit Free Press reports.

EDGE Analysis

Zimmermann was moved to the 10-day injured list Friday, although he won't be ready to return to game action after the 10-day minimum. Another update on the right-hander's status should come when he resumes throwing.

Zimmermann was placed on the 10-day injured list Friday with a UCL sprain in his right elbow.

EDGE Analysis

Zimmermann lasted only three innings during Thursday's start as he felt elbow discomfort, and further testing Friday didn't provide encouraging news. The veteran right-hander will be eligible to come off the injured list May 7, but he seems likely to face a longer absence.

Zimmermann (0-4) took the loss and allowed five runs on five hits and three walks Thursday night against the Red Sox. He struck out two over three innings.

EDGE Analysis

Zimmermann's start didn't last long, as he surrendered two runs in the second and three more in the third before getting yanked. He racked up 77 pitches through just three frames. The 32-year-old right-hander has hit a rough patch of late, giving up four or more runs in each of his previous three outings, despite allowing just one run over his first two starts of 2019. Zimmermann is scheduled to toe the rubber next against the Phillies on Wednesday.

Zimmermann (0-3) allowed five runs on six hits and four walks across 6.1 innings to take the loss Friday against the White Sox. He struck out four.

EDGE Analysis

Zimmermann actually pitched decently through six innings, holding the White Sox to just two runs. However, he started the seventh with a walk and a single to get into trouble. The righty followed that with a strikeout, but another single scored two runs to make it 4-1 and chase ZImmermann from the game. The 32-year-old started the season with back-to-back gems, but he's now allowed four earned runs or more in his last three outings. Zimmermann will look to get back on track in his next start, which is scheduled for Wednesday against the Red Sox at Fenway Park.
