The Edmonton Eskimos have added to an already fierce rivalry with a series of radio ads trash talking Saskatchewan Roughriders fans.

The Roughriders and Eskimos battle for second place in the CFL West on Friday. With thousands of Rider fans expected to pour into Commonwealth Stadium, the Eskimos have upped the ante in an effort to get more Edmonton fans to the game.

In one radio ad, the Eskimos talk about “the irritating Saskatchewan Roughriders fan.” It then goes on to call Rider fans “loud, obnoxious" and describes a fan who "somehow manages to brag about his team winning  a dominant four championships in just over a century.”

Another ad starts by saying, “The Saskatchewan Roughriders have fantastic fans," but goes on to say, “Even if they are horrible human beings.”

Kickoff is Friday night at 8 p.m. CST.
