Appending a table by adding only records who are not duplicates

I am designing a database program for a Fantasy hockey league. table A gets
Players current stats from an excel spredsheet it is linked to. Table B is
to be updated with the current stats. Now updating existing records I have
no issues with. If a player is new or added, I need him to also be added to
table B. Here is the kicker, Table B has one more column for status (Free
Agent, or what team owns that player). I don't want this information to
change. I have tried to use an append query but that way not only adds the
new guy to table B, it adds every other guy again. A make table query would
be perfect, but it will eliminate that additional status column. Is there a
way to get an append query to do more of a differential append that will
append only those players that are currently not on Table B?

Thanks
