The project was absent from the cable channel's official fall schedule, which was confirmed earlier this week.
However, a spokeswoman for the network has since announced that TNT executives will make a final decision on the show's future in the next few weeks, after viewing the completed pilot episode.
The show, which will feature original Dallas stars Patrick Duffy, Linda Gray and Larry Hagman, is not expected to premiere before 2012 if it receives a full series commission.
Brenda Strong, Jesse Metcalfe, Julie Gonzalo, Josh Henderson and Jordana Brewster will also appear in the reboot.
Filming on the pilot episode, which took place at Southfork Ranch in Collin County, Texas, wrapped last Friday.
