Fortunately, Hurricane Sandy will not interrupt “Monday Night Football” as the San Francisco 49ers and Arizona Cardinals meet.

But the massive storm is impacting the league. NFL.com reports that the Baltimore Ravens, New York Giants, New York Jets and Philadelphia Eagles have all instructed players and non-football personnel to stay at home. The NFL offices in New York will be closed for all non-essential personnel and regular transactions will take place.

According to the report, the Giants and Ravens will have coaches and front office personnel in the office for work today. This isn’t totally unusual. A lot of teams have moved to giving players Mondays off and allowing coaches to review game film and begin preparations for the coming week. Players then show up for film study beginning on Tuesdays, what was typically their day off in the past.

The Jets are heading into their bye and were originally going to practice today and Tuesday. Instead, they have been told to return next Monday as they will get the entire week off.

It is not known when the Patriots will return from their game in London.
