The team said Kluber, who hasn't pitched in the majors since he broke his arm during a start on May 1, was taken out of Sunday's game for Triple-A Columbus in Charlotte, North Carolina, for precautionary reasons. The two-time Cy Young winner was making his third start as he attempts to return from the injury.
Kluber walked two and didn't allow a run in his one inning. The 33-year-old was scheduled to spend Monday in Cleveland -- an off day for the Indians -- before rejoining the club in New York.
It's not yet known if Kluber's abdominal issue is a setback. The Indians have been hoping that he might be able to pitch for them during their September playoff push.
Kluber won the Cy Young in 2014 and 2017.
