NEW YORK -- Two-time Cy Young winner Corey Kluber is expected to be shut down for two weeks after he left his rehab start Sunday for Class AAA Columbus with an injury to his left abdominal muscle.

Kluber was in Cleveland on Monday undergoing an MRI and other tests. The Indians are expected to make an announcement on his condition Tuesday before they open a three-game series against the Mets at Citi Field.

The question now is: Will Kluber have enough time to make a couple of regular-season starts and be available should the Indians make the postseason? If he’s shut down for two weeks that would probably make him unavailable through August. Then he’d need 10 to 14 days to build his arm and body back up.

That’s cutting it close, especially with the Indians playing from behind. They trailed the Twins by 2 1/2 games in the AL Central on Monday before Minnesota played against the White Sox in Chicago. In the wild card, the Indians had a one-game lead on the first spot over Tampa Bay.

Kluber, who has not pitched in the big leagues since suffering a broken right forearm on May 1, was scheduled to throw 80 to 85 pitches on Sunday. If all went well, there was a chance he could have rejoined the Tribe’s rotation Friday against Kansas City at Progressive Field.

On Sunday, Kluber was removed after one inning and 20 pitches because he felt tightness in his left abdominal area. It was Kluber’s third rehab start.

This has been a tough season for Tribe starters. Mike Clevinger strained a muscle in his upper back in his second start of the season. Kluber suffered the broken ulna bone in his right arm when he was hit by a line drive on May 1 against the Marlins. Carlos Carrasco was diagnosed chronic myeloid leukemia and made his first rehab start Monday night at Class AA Akron. Clevinger has since rejoined the rotation.

Because of the injuries and illness, the Indians were forced to dip into the minor leagues and Zach Plesac, Adam Civale and Adam Plutko have pitched well.
