I was just wondering why in the Cavs Hornets game last night... 1/16/09...did the Hornets have diff. jerseys?

INstead of having that turquoise, gold and white... they were blue, red and white with "Bucs" across the front. I know that the Cavs lately have been sporting their throwbacks with the gold and maroon at Home and blue with gold and maroon away, bt Ive never seen this from the Hornets...is that their throwback?? Oh and lastly, I didn't get to see the whole ame but I saw that CP3 and Posey were ejected. I saw highlights of Posey's had foul on Mo Williams but what did CP do??
