The Indians have been contacted by rival clubs interested in pitcher Justin Masterson before the July 31 trade deadline, the Cleveland Plain Dealer reports.

Masterson has been on the disabled list since July 8 because of right knee soreness. He went 4-6 with a 5.51 ERA in 19 starts before the injury. He will make his second minor-league rehab start Friday at Triple-A Columbus.

"We told him to get after it. We think that would be good for him. Just to get after it, let it fly and see how far he could carry that into the game," manager Terry Francona said.
