Looks like machine damage from production most likely. The quality control for cards haven't been the greatest the past few years.
I got two cards from a basketball card blaster a few years ago that had the top right corners damaged pretty badly. The insert set was called Run the Gauntlet. At first I thought it was done on purpose due to the name of the insert. I ended up sending them to Panini and got replacements returned.
I also got rookie card of James Wiseman recently from a pack of Chronicles and it has a line right down the middle of the card.
