Tickets to professional sporting events have provisions stating you can be ejected for recording the event. While these are basically never enforced, I could see trying to stream the entire game be a good reason for the venue to start enforcing it.
Similarly, the broadcasts of sporting events have a disclaimer saying you can't rebroadcast or retransmit it in any way, but I have no idea if that is legally binding.
