Newcastle is on a shortlist of cities to host both of European club rugby union's showpiece finals in 2018.
The city is bidding to stage the finals of the Champions Cup, Challenge Cup and Challenge Cup qualifying competition.
If successful, Newcastle United's St James' Park would stage the 2018 European Champions Cup final.
European Professional Club Rugby have not disclosed the rival bids and the next stage of the selection process will see EPCR visit candidate cities.
A final decision is due to be made in April 2017.
