Per him:

This is interesting and perhaps unexpected.

Hill, you may recall, got into hot water in January when he made a racially insensitive remark while doing in-arena hosting for the Philadelphia Wings. That was the “snip the ponytail” comment made in reference to a Native American player on the other team. Hill apologized and even traveled to Allentown’s Museum of Indian Culture in a show of goodwill and remorse, but was removed from his role as the Wings’ announcer and suspended from all Wells Fargo Center-related assignments anyway.

I don’t know much of what happened beyond that, but it seems like he’ll be clarifying at some point in the future.
