It is of course subject to local regulations which of course Governor Newsom has taken a stiffer stance on than other governors. I understand that this is a players only time and coaches aren't permitted so overall the Niners players can keep to their normal at-home routines which shouldn't set the team back too much. However, do we have a plan 'B' once things get going? Training camp in another state? Any word on this?
