It's out with the old and in with the new for football fans in Saskatchewan.

But the 13th man will have plenty of opportunities to say goodbye to the aging Mosaic Stadium.

A farewell season kickoff celebration, including a barbecue and entertainment, will be held at the stadium on May 21, the City of Regina announced Wednesday.

Two contests are also being launched. Community groups can submit a proposal for a farewell event to be hosted in the old stadium. The public is also being asked to pitch ideas for a commemorative art piece that will be hung in the new stadium.

The deadline for submissions is May 31. More information is available online at regina.ca/residents/farewell-season.

The $278-million new Mosaic Stadium is slated to open by the start of the 2017 CFL season.
