Rivera (leg) was activated from the minor-league disabled list Tuesday.
Rivera is back in action with Low-A Lake County after missing more than a month with a leg injury. Prior to landing on the disabled list, the 22-year-old was hitting .185/.421/.259 across 10 games with the Captains.
Rivera was placed on the 7-day disabled list with right leg soreness.
It doesn't appear as though Rivera will be forced to miss an extended period of time, but the catcher is set to miss at least a week due to this injury. Over 10 games with Low-A Lake County this season, Rivera is hitting .185/.421/.259 with two doubles and two RBI.
