The Marlins placed Fairbanks on the 15-day injured list Tuesday with right medial nerve irritation.
Fairbanks had to be removed from Monday's appearance versus the Red Sox after just one batter due to the issue. He is scheduled to see a specialist Tuesday, per Christina De Nicola of MLB.com, and more could be known regarding a timeline for the reliever following that visit. While Fairbanks is sidelined, any of Michael Petersen, Calvin Faucher and Josh Ekness could see closing opportunities.
