Masterson was placed on the disabled list earlier this month with a right knee injury that's been bothering him since his second start of the season. He shouldn't need more than 1-2 rehab starts before rejoining the Indians' rotation.

In his return to the rotation, Justin Masterson (knee) allowed three runs and lasted just three innings in Tuesday's no-decision against the Dodgers.

Masterson, whose Sunday start was skipped, was cleared to rejoin the rotation after throwing a pain-free bullpen session Saturday. Indians pitching coach Mickey Callaway complimented Masterson's velocity, command and movement in that session. Tonight, he was all over the place, striking out seven but walking three and coughing up seven hits, including a homer. He was yanked after 85 pitches. The right-hander is coming off an inconsistent month in which he logged a 1.42 ERA to win his first two starts of June, but limped to an 0-1 record with a 7.62 ERA in his last three outings. Masterson (4-5, 5.16 ERA) hosts the Yankees next week.

Justin Masterson revealed Wednesday that the right knee issue that will force him to miss his start Sunday has been a problem since his second outing of the season.

It could help explain why Masterson's velocity has been down and his ERA is up to 5.03. "I don't know," said Masterson. "It's just been a little nagging. Maybe it's taken (away) a little of the power and consistency?" The Indians might be best off shutting Masterson down for a while, but the hope is that he'll feel well enough to start Tuesday or Wednesday. T.J. House is likely to be called up to start Sunday.

Justin Masterson will miss Sunday's start with a sore right knee.

It could partially explain why he lasted just four innings in Tuesday's start against the Diamondbacks. The right-hander will only be pushed back two days due to the ailment, so at this point it doesn't appear Masterson will need a trip to the disabled list. The Indians will need to find a spot starter for Sunday's game in the meantime.

Justin Masterson was chased out of Tuesday's against the Diamondbacks after giving up five runs over four innings.

Masterson was looking to build upon Thursday's strong start (7 IP, 1 ER) but instead penned another chapter of a disappointing 2014 campaign. He walked four and gave up seven hits in tonight's no-decision to push his ERA to 5.03. Masterson entered this evening with a 3.32 ERA in June, but the tall right-hander isn't showing enough consistency yet to be trustworthy in mixed leagues. Masterson gets the ball in Seattle on Sunday.
