Very sad that OSU couldn't put out a release before Thursday ...

From a Pac-12 Conference release today ... and a very helpful and timely University of Washington release ...
OSU's Session 2 will be broadcast on the Big Ten Network on TV at 8pm PT on Friday 1/6 (as will Session 1 at 2pm on 1/6 and Session 4 at 6pm on 1/7 ... Session 3 will be on the BTN+ streaming service at Noon PT on 1/7, & tape-delayed on BTN TV 1/8 at 4pm PT) ... the BTN requires a subscription (I think for my Xfinity subscription I can add it for $9.95/month ... another option is to get a FREE trial of YouTube TV (with BTN included) and then cancel on Saturday.)
With a subscription you can also watch the BTN on the "Fox Sports" app.

Here is a guide to other options (including some with free trials) without a cable subscription ...
How To Watch Big Ten Network without Cable

If you have a subscription to BTN you can also watch on the “Fox Sports” app ...
App Store ; Google Play ... or (possibly?) on the Fox Sports Watch page in a browser?
(For Session 3 on BTN+ you can get a separate subscription for as low as $9.95/month for a single school’s games … Iowa. I don’t know if this is included in a BTN Network subscription?)
