Warren Blake, president of the Jamaica Athletics Administrative Association, said after the trials a month ago, that despite having thrown the qualifying standard, Morgan did not warrant an automatic spot as he placed fourth.
A three-member panel from the Court of Arbitration for Sport (CAS) will rule whether he can join the team before the athletics events start on Aug. 12.
While documents from CAS did not say when the hearing would take place, the athlete told Reuters via text message it was due to be held on Tuesday.
"The history with Morgan is that he only throws the automatic qualifying standard at a particular meet early in the season and he never repeats himself, so it was the view of the selection committee that he should be chosen," Blake said at the time.
