I barely know what to say. I just know it was too much of a bizarre situation NOT to write about. According to the TNT broadcast, it may have been some form of protest she was trying? Sideline reporter Allie LaForce provided the "glue" detail. Unclear if it was actually superglue, Elmer's liquid, a glue stick, a glue gun…I don't know.

YIKES.
Anyway, carry on with your lives.
