SAN FRANCISCO (AP) — The Pac-12 has established cancellation and tiebreaker policies for its virus-truncated football season. The conference announced that a minimum threshold of at least 53 scholarship players must be available for any team to participate in a game. The game would be rescheduled or declared a no contest if a school elects not to play the game shorthanded. The Pac-12′s seven-game, conference-only season is scheduled to start Nov. 7 and the conference is taking potential cancellations into consideration in its tiebreaker policies.
