Was somebody hacking CSNNE's Celtics broadcast on Monday?

In the midst of Kelly Olynyk's career-high 30 points in the Celtics win over the lowly Sixers on Monday, something very odd happened during the CSNNE broadcast.  While airing a replay of an Olynyk dunk, a strange yellow image briefly appeared on the lower right corner of the screen:

I don't know what that is, but I have a guess at what it might be.  Was it the work of a disgruntled employee playing a practical joke?  A slightly deranged internet hacker messing with the broadcast (maybe one of those total idiot or sneaky-genius Miller Lite ad people)?

No, it was just a telestrating attempt gone wrong, as color commentator Cedric Maxwell said he loved the pass that set up the dunk, and tried to highlight it with a heart.  At least I think it's a heart...
