Check website becuz as a vendor, I have seen on more than one occassion tripod & huge camera toting people come through (all though whether or not they were pro crew, students, amateurs, etc I fo not know).
As long as the lens is not removable you are allowed to bring it in, I brought a tripod in but it fit in the palm of my hand.
You can normally bring cameras to any stadium as long as its not a professional camera and i don't believe you are allowed to bring tripod's
