The 27-year-old, who married her long-term partner Andy Hill last month, has competed just once since winning heptathlon gold at London 2012. This came at the Leeds Metropolitan University Invitation in the javelin.
Ennis was due to open her 2013 season at Edinburgh's Meadowbank Sports Centre on June 8 in a UK Women's Athletic League Premier Division meet and compete in the hurdles, javelin and long jump.
But a stiff left Achilles means her return to action has been put back.
