From Bruce's blog yesterday:
Now that it has sold out Sunday's Red-Blue Game, Arizona announced today that the scrimmage will be streamed live for free on the Pac-12's website via this link pac-12.com
The webcast will require no login, so even those stuck in DirecTV/Pac-12 Networks purgatory should be able to view the event without trouble.
There were two hurdles to the webcast being announced.
First, UA wanted to make sure that the game sold out before giving it away, to ensure the best possible crowd for the many UA recruiting targets to be on hand.
Then once it sold out, UA had to get approval for the Pac-12 to stream the game, since the conference now owns all broadcast rights to member events, even (as in this case) a glorified practice.
The webcast will start at 2 p.m., and the scrimmage will tipoff at about 2:20 p.m. after the highlight videos, introductions, induction of Andre Iguodala into the Ring of Honor (for winning Olympic gold) and dunk contest have taken place. The 1988 Final Four team introduced before the game and will be recognized at halftime.
The scrimmage is scheduled for two 12-minute halves.
