A player reportedly set for a summer transfer to Leeds United was within three-and-a-half miles of the Whites' training ground earlier.
However, neither club has yet made comment on a deal the newspaper claimed will be worth £150,000 up front and a potential £400,000 in total.
Nevertheless, it appears there could be some substance to the Scottish Sun's report - if McKinstry's latest Instagram post is anything to go by.
The 16-year-old added a photo to his story from a location in Wetherby, West Yorkshire, which is less than 10 minutes' drive from Leeds' Thorp Arch training ground.
The reason for McKinstry's visit remains to be seen - although it would be some coincidence if it was not Leeds United related.
The lifelong Motherwell fan is still awaiting his senior debut, but has made the bench this season and won Scotland caps at under-17 level.
