Kluber underwent additional tests on his strained oblique Friday, Ryan Lewis of the Akron Beacon Journal reports.

EDGE Analysis

Additional testing is generally a cause for concern, but in this case, the Indians are apparently trying to see if they can move up Kluber's target return date. Kluber's status will be updated further once the results of Friday's exam are released.

Kluber underwent an MRI on Monday and was diagnosed with an internal oblique strain.

EDGE Analysis

Following this diagnosis, the timetable for Kluber's return is unknown, though he's been shut down from throwing and will be re-evaluated in two weeks to determine whether he's ready to begin a rehab program. He suffered the injury during a rehab start for Triple-A Columbus on Sunday.

Kluber will likely be shut down from throwing for the next two weeks after leaving Sunday's rehab start for Triple-A Columbus due to an abdominal injury, Paul Hoynes of Cleveland.com reports.

EDGE Analysis

Kluber made his way back to Cleveland on Monday to undergo an MRI, though the team isn't expected to announce the results until Tuesday. Assuming the right-hander is indeed shut down for the next two weeks, his timetable would likely be pushed back to mid-September, considering he'd need at least a few more rehab starts before being activated from the IL.

Kluber (forearm) was removed after the first inning of Sunday's rehab start for Double-A Akron due to abdominal tightness, Mandy Bell of MLB.com reports.

EDGE Analysis

Kluber's removal was reportedly precautionary, but he'll likely head for further evaluation to rule out a serious injury. It remains to be seen if this setback will have a major impact on his timetable.

Kluber (forearm) tossed four innings Tuesday in a rehab start for Double-A Akron, allowing one run on two hits and a walk while striking out six.

EDGE Analysis

Kluber showed improvement in what was his second rehab start over the past week, retiring the first 10 batters he faced before allowing a solo home run in the fourth inning. He ran his pitch count up to 60 but once again struggled to find the zone, registering 36 strikes. Per Zack Meisel of The Athletic, the right-hander is scheduled to start for Triple-A Columbus on Sunday. Kluber will presumably increase his pitch count up to around 80 in Sunday's outing, which could be his last before rejoining the big-league rotation.

Kluber (forearm) tossed three innings Thursday in his first rehab start for Triple-A Columbus, giving up two runs on two hits and a walk while striking out two.

EDGE Analysis

While making his first appearance at any level since May 1, Kluber unsurprisingly didn't have his best command or control in the outing, serving up two home runs while pumping in 24 of 41 pitches for strikes. According to Paul Hoynes of The Cleveland Plain Dealer, Kluber's two-seam fastball sat around 89-to-90 mph, which was down a tick or two from what he sported over his seven starts with Cleveland before fracturing his right forearm. On a positive note, Kluber retired the final five batters he faced and completed a bullpen session afterward to push his pitch count for the day to around 55. The two-time Cy Young Award winner remains on track to return from the 60-day injured list in the second half of August. He's expected to throw around 65 pitches in his second rehab start, which will come Tuesday for Double-A Akron.

Kluber (forearm) is scheduled to make his first rehab start Thursday with Triple-A Columbus, Anthony Castrovince of MLB.com reports.

EDGE Analysis

Word surfaced Saturday indicating that Kluber would kick off his rehab assignment during the upcoming weekend, but it wasn't known what affiliate he would pitch for until Sunday. With Kluber coming out of his two-inning simulated game over the weekend without incident, he'll bypass a trip to a lower-level affiliate and instead head to directly to Triple-A, perhaps signaling that the Indians don't expect him to require a lengthy rehab stint. Cleveland will likely see how Kluber looks Thursday before determining whether he's fit to immediately re-enter the rotation on a lightened pitch count or if he'll need at least one more start in the minors to build up his arm following the lengthy absence.

Kluber (forearm) will begin a minor-league rehab assignment Thursday, Zack Meisel of The Athletic reports.

EDGE Analysis

He was apparently sitting around 88-89 mph with his fastball in a 35-pitch sim game Saturday, Ryan Lewis of the Akron Beacon Journal reports. It is unclear where he will begin his assignment, but he is on track to return to the big-league rotation in late August or early September.

Kluber (forearm) successfully threw a 35-pitch simulated game Saturday, Ryan Lewis of the Akron Beacon Journal reports.

EDGE Analysis

Kluber threw all of his pitches against Double-A hitters and felt well afterwards, admitting that he's passed the point of feeling hesitant when throwing. The 33-year-old is nearing a rehab assignment that would put him on pace to rejoin the Cleveland rotation later this month.

Kluber (forearm) will throw a simulated game Saturday, Ryan Lewis of the Akron Beacon Journal reports.

EDGE Analysis

A broken arm has kept Kluber out of game action since the start of May. If his session Saturday goes well, his next time throwing could come as part of a rehab assignment.
