You can not watch it on ESPN3 as it was not broadcast on their family of networks.
The only place would be BTN2GO.com, where they stream all of the BTN games (basically the BTN's version of ESPN3). However, the availability of this depends on your Internet provider. For example, it is unavailable to Mediacom subscribers.
Everything I have see is that it will NOT be shown on the BTN this week, as is usually the case.
I've looked at the schedule most of the week hoping to catch it on BTN but haven't seen it listed at all, even early am as I'm usually up feeding my baby, looks like with volleyball season going they are showing more vb games than replays right now.
