Last year there were changes midseason to positional eligibility (Cordarelle went from WR to RB, Juwan Johnson from WR to TE, know at a minimum those two) and it was generally around Week 4 I believe.
Which is to say it could happen but it’s up to the data provider per Niv. Would not be surprised to see him move to RB or QB at some point and lose TE.
EDIT: Went to find the post from last year and see that you actually started the topic haha. Position Change Football - #12 by walt526
