Myers pitched five innings of three-run ball against Houston on Friday, then said he had been dealing with a problem with the flexor tendon in his arm since spring training. He is 0-3 with an 8.02 ERA in three starts and one relief appearances this season, allowing 10 homers.
The Indians placed Myers on the disabled list Sunday and made the move retroactive to Saturday. The pitcher returned to Cleveland over the weekend, where he was diagnosed with right elbow tendinitis and a mild ulnar collateral ligament sprain. He will stop throwing for two weeks and then be evaluated again.
"It is what it is. I don't think he felt like it was going to be worse than that," manager Terry Francona said before a 3-2 victory over the Chicago White Sox on Monday. "The two weeks down, and then hopefully get him on a good throwing program, get him back on the mound helping us."
The 32-year-old Myers agreed to a $7 million, one-year contract in January that includes an $8 million club option for 2014, part of an active offseason for the Indians. He is 97-96 with a 4.25 ERA in 381 career games.
"I think what he said in spring was normal soreness that he thought he could pitch through, and for whatever reason, it didn't go that way this time," Francona said.
Right-hander Corey Kluber will start in Myers' place Wednesday against the White Sox.
"He understands completely that he had our blessing to be at home, and our thoughts and our prayers were always with him, and hopefully even our actions," Francona said, "and that we welcome him back. At the same time, we will think about his wife and his family. Hopefully now this is where these guys can help him."
All-Star shortstop Asdrubal Cabrera returned to the lineup after missing Sunday's 5-4 victory at Houston with a bruised left wrist. He had a big two-run single with two outs in the eighth inning to lift Cleveland to its third consecutive win.
Cabrera was injured when he fell down the steps on the way to the dugout Saturday.
Francona also said catcher Lou Marson will rejoin the team Tuesday and be activated Wednesday. Marson went on the disabled list April 9 after he injured his neck in a home-plate collision with Tampa Bay outfielder Desmond Jennings.
Yan Gomes was promoted the same day Marson went on the DL, and Francona indicated the young catcher is probably headed back to the minors.
"We've talked to Yan about this," he said. "I mean we haven't made a move yet, but he understands that he does not need to be sitting here not playing. It's not in his interest for his future."
