Nunez (right hamstring strain) is a likely option for a short rehab stint when his injury heals, but Gardenhire expected him to be available when the Twins start their homestand on June 30 against the Royals.
The 27-year-old was placed on the disabled list on Thursday, retroactive to June 15, while Plouffe has been there since June 15, so they're both eligible to return on June 30.
"I don't know if they're even going to need rehab," Gardenhire said. "When we get back from this trip, they should be both ready. Whether they're going to rehab or not, we're not decided yet.
Minnesota currently has 13 pitchers on its active roster, a number that Gardenhire would like to trim.
"You can always go get a pitcher if you need one," he said. "I'd like to have an extra bench guy."
