“We’re really sad to see Hindy go,” Gallagher said.
“Nick is at a stage in his career where security and playing opportunities are a real priority.
"For these reasons, he expressed to us a desire to pursue the next phase of his career at Essendon, and we were willing to support his wishes to do so.
“We wish him and Telisha all the best for this next chapter of their lives and career.”
Hind registered 21 games for the red, white and black after being selected as a mature-ager with pick No. 54 in 2018.
