That's because Spurs manager Roberto de Zerbi wants to cast an eye over the winger during pre-season before deciding what to do with him next season.
The Premier League giants have already decided they do not want to sell the 18-year-old permanently this summer, according to Football London.
But the Italian would like to watch Moore in training before reaching a verdict on whether to keep him as part of his squad next season or send him out on loan again.
That means Rangers could be forced to wait until late in the transfer window if they would like the skilful wide man to return after his impressive showing last season, which saw him pick up a club young player of the year award as well as PFA Scotland's.
Moore scored seven and added four assists in 47 matches.
A host of other clubs are interested in loaning the young talent for next season, adding another layer of complexity to the situation.
Spurs return to training on July 10th.
Tottenham avoided relegation to the Championship, a fate that could have seen Moore afforded more opportunities going forward.
