It has previously been reported that centre Brian Kelly isn't vaccinated, however, he wouldn't confirm nor deny the reports in a report yesterday when speaking to AAP.

The Titans have previously claimed the club will be 100 per cent vaccinated by Christmas, however, Kelly said he was working with the club at the current time.
"All of Australia is all under pressure with all that stuff," Kelly said.
"But with myself, I just have good communication with the club and just take it step by step."
