What are my rights concerning selling goods that I wasn't aware of that was unlicensed by Nike for the NFL.

You are most likely out of luck. You can sue the Chinese company but I suspect that would be a waste of time.  Hopefully Nike won't sue you for unauthorized use of their logo and will be satisfied that the merchandise was removed. You won't need a lawyer unless Nike sues, or unless Nike tries to have your criminally prosecuted.     Many foreign countries do nothing in the area of trademark/tradename protection so if you do business with companies overseas, it's a risk you take.  You can always request a supplier produce proof of licensing from the company...but even that can be forged, so call the producer (Nike) to confirm it's real..   If a price seems too good to be  true on stuff like this, that's a huge flag and if a supplier can't produce proof of authorization, that's a second big red flag.
