Judge inferior (after knocking back any number) a port (6)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

J(judge), NAFF(inferior) with the N(any number) moved to the back, then A.  As I alluded to before, I only know of this place because their team, the Jaffna Kings (originally the Jaffna Stallions) won the first three instalments of the Sri Lanka Premier League (they got knocked out in the eliminator this year). The former Australian batsman Chris Lynn plays for them.  Is it known for anything else?
