Hafner went on the 15-day disabled list on Wednesday with inflammation in the knee. He’s hitting a career-worst .242 in 39 games.

The 34-year-old Hafner is in the last season of a six-year, $66-million deal. The Indians have seven players on the disabled list.

Left-handed reliever Scott Barnes was recalled from Triple-A Columbus to take Hafner’s roster spot.
