So, we asked him about that ... and this video could have Indians Nation super worried!

Here's the deal ... Lindor was out in NYC this weekend and was super nice to our camera guy and other fans, talking about everything MLB related.

He gave love to Cleveland and called it "my home" -- but when we pressed him about staying with the Indians long term ... well, that's when the cat got his tongue.

Watch the video ... Lindor is chatty about every other topic except when we specifically asked about his career in Cleveland.

Of course, Lindor -- who's one of the 10 best hitters in the sport -- has a very uncertain future in Cleveland ... Indians owner Paul Dolan has already hinted he ain't willing to give the shortstop the FAT contract extension he probably deserves.

In fact, Dolan famously said before this past season, "Enjoy him. We control him for three more years. Enjoy him and then we’ll see what happens."

So, is Lindor's silence speaking volumes ... or is this a big ol' nothingburger?

It's not just the Indians fans in our office feeling some sort of way ... and even the non-CLE crowd was shocked by the non-answer answer.
