As conference realignment rumors swirl, the presidents of the Big Ten will participate in a conference call Friday.

The news of the B1G call comes from Associated Press College Football Writer Ralph D. Russo. The call is presumed to be about expansion. Oregon and Washington, 2 schools that have been linked to the B1G, had not received invitations as of Friday morning.

There have been twists and turns over the past few hours regarding Oregon’s plans. Overnight, there was a report in The Oregonian that Oregon was prepared to accept a B1G invitation. Then, Friday morning, it appeared Oregon was leaning toward staying in the Pac-12 – until the conference’s new deal was not signed.

The college football world is watching closely to see what shakes out in the last round of realignment between the B1G, Pac-12 and Big 12.
