I think that's just the CHL/NHL agreement. Nylander can play in the AHL, he's not in the CHL.
And I read there is a clause in his in contract that said the Leafs had to have him in NHL/AHL by January 16th, or something or like that.

Leaf asst g.m Kyle Dubas says "no chance" that Nylander will play for the Leafs this season. His development will take priority. #TMLtalk
Aselvana was replaced in the BBDL a few weeks ago for "not being able to keep up with the league", was replaced in this league after his not setting lineups cost him a matchup vs BTS.
