Warriors and Kiwis star Shaun Johnson revealed his favourite swear word in an online questionnaire for an NRL player profile.

Embarrassed NRL bosses have removed controversial player profiles after a questionnaire asking them their favourite swear words backfired.

In what was intended to be a light-hearted approach, players were asked what their favourite swear words were in interviews in a question and answer format on the official NRL website.

Australian news agencies today reported that Warriors star Shaun Johnson allegedly came up with "F…wit". Knights captain Kurt Gidley opted for "F…" and Broncos forward Sam Thaiday said his "starts with an s and ends in a t".

Thaiday also revealed that fart noises were the sounds he both loves and hates.

News.com.au highlighted the poor-taste profiles today after they had been exposed by Australian TV channel Seven News.

The profiles had apparently been on the site for several months, but had gone unnoticed with league in the offseason.

When Seven News questioned the appropriateness of the profiles for children wanting to read more about their favourite players, NRL bosses apparently contacted the website's editor to review the content.

The relevant pages appear to have been removed.

For a sport constantly embroiled in off-field incidents, it was another bad look leading into a new season.
