Fiona, along with Graham Vard, will be attending Saturday's RBS 6 Nations game between Ireland and Italy, and the pair will also be present at the official IRFU post-match team reception.
Fiona said: "Our team are really looking forward to joining the IRFU's league, Bud Light Tag, this year. We've heard lots of great things about it, being great value, great fun and professionally run.
"I was delighted to learn I'd been drawn. This will be quite a special start to the year and I'm very excited about the day itself, having never experienced a rugby match at Croke Park."
To enter the draw, teams must submit a minimum of 10 players' correct names when registering a team into a Bud Light Tag league online.
All names go into the hat for a draw where they can win prizes such as those that Fiona has won.
The team must be fully registered and paid as only complete registrations are eligible for the draw.
Winners for the next two draws will be notified by email, SMS and announced on the following dates:
March 1 - Ireland v Wales, Croke Park, 2.30pm, Saturday, March 13
March 8 - Ireland v Scotland, Croke Park, 5.00pm, Saturday, March 20
