OAKLAND -- Right-hander Danny Salazar will have arthroscopic surgery on his right shoulder on Monday. Salazar has been on the disabled list all season.

Dr. Keith Meister, team physician for the Texas Rangers, will do the surgery. Meister examined Salazar's shoulder in May and gave him a PRP injection. At the time Meister confirmed the Indians' diagnosis that Salazar was suffering from right shoulder impingement tendinitis.

Salazar, at the end of May, came to Cleveland for an MRI and more tests on the shoulder. He received a cortisone shot and was sent back to Goodyear, Ariz., to resume his throwing program.

On Friday manager Terry Francona hinted that something was wrong with Salazar. He said the organization was gathering information and that an announcement would be made in the near future.

Salazar reported to spring training with a sore right shoulder in February. He has spent the season rehabbing at their spring training site in Goodyear.

The Indians announced there is no timetable for Salazar's return, but it's hard to see him pitching anytime this season given that he hasn't pitched in a game since last year.

Salazar, 28, hasn't been healthy since the first half of the 2016 season when he pitched well enough to make the All-Star team. He has struggled with right forearm, elbow and shoulder soreness since.

He made two trips to the disabled list last year with shoulder and elbow soreness. Salazar was 5-6 with 4.28 ERA in 23 games, including 19 starts, last year.

The Indians have appeared in the postseason in 2016 and 2017, but Salazar has not been available as a starter. He did pitch out of the bullpen, making two appearances in 2016 and one in 2017.

Salazar, in his career with the Indians, is 38-33 with a 3.82 ERA. He has 686 strikeouts in 587 1/3 innings.

This will be the second surgery in Salazar's career. He underwent Tommy John surgery on his right elbow in 2010 while still in the minors.
