Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_18 (played INTEGER, lost VARCHAR, goals_against VARCHAR, team VARCHAR)

### Question ###
What is the average Played, when Goals Against is less than 63, when Team is "Nelson", and when Lost is greater than 16?

### Accurate SQL ###

SELECT AVG(played) FROM table_name_18 WHERE goals_against < 63 AND team = "nelson" AND lost > 16
