Anyone whose name is "T-Dogg" and doesn't speak in the episodes much is not a character who is going to be around forever.
I'm pretty sure the black guy is only being kept around for one thing: so Merle can kill him.
Other than that, like you said, he doesn't contribute anything meaningful. His death at the hands of Merle though would be significant and meaningful to the show and ratings though.
