Over the 2014–15 season, Navarro experienced several injury problems with his right leg. In late December 2014, it was announced that he would miss up to six weeks of action, due to a torn muscle in his right thigh. On June 29, 2015, it was announced by Barcelona that Navarro would miss three months of game action, due to plantar fasciitis on his right foot. Those injuries negatively impacted his performances over the season, in which he had averages of 10.5 points and 3.1 assists per game, on 37% shooting from the field overall, in 17 EuroLeague 2014–15 season games.
