In March 2014, Vlašić made her comeback at an international championship since the 2011 World Championships at the World Indoor Championships. She placed 6th with 1.94 m. Due to a jumper's knee injury in her left knee, she had to withdraw from the European championships in Zürich where she was one of the favorites alongside Russia's Mariya Kuchina, due to her two recent wins in Paris and London with 2.00 m.
