sql-server-2005

I have a database which had all it's foreign-key relationships dropped at some unknown time in the past (don't ask). I have an old copy of the database which isn't good to restore from, but the schema has the relationships. I'm working from that to create a script to restore the keys.

In updating the tables, I've had to drop statistics from several tables. Do I need to manually recreate those, or can I just run the statistics update procedure when all the tables are updated?
