Zumsteim you beat me to it, ha ha ha.
So, it used in one sentence:
Tulane sports beat reporter for the Times Picayune will be the guest speaker.
One aside note: a beat reporter can be either one that cover sports in general or the one that beat a given sport (perhaps the size of the media will have an influence on this.). A beat reporter can be also one specialized in one area of interest, could be from police/education/environment/shopping, to education, technology...and the list goes on and on.
