Kipnis hasn't played this season because of a low-grade right calf strain. He recently completed a rehab assignment with Triple-A Columbus.
In a separate move, the Indians designated infielder Brad Miller for assignment.
Entering his ninth MLB season, Kipnis has played his entire career with the Indians. He was an All-Star in 2013 and 2015, but batted a career-worst .230 in 147 games last season.
