The Roughriders returned to Mosaic Stadium on Monday night with a decisive victory over the Toronto Argonauts. But while fans were happy to welcome their Riders home, they had a few concerns about Gainer’s off-season makeover.

The mascot is a little slimmer, and perhaps a little scarier, heading into this year’s CFL season.

We've worked all off-season to be under the bright lights. Our favourite gopher is no exception.



Now, Gainer is more #CFLGameday ready than he's ever been before....

Online reaction included fans fearing he would “haunt [their] dreams”, while others said he’s “not my Gainer.”

Some compared the new and improved Gainer to Gritty, the infamous mascot of the Philadelphia Flyers.

One disgruntled fan has even launched a petition calling on the Riders to bring back the former Gainer. It had collected more than 1,000 signatures as of Tuesday morning.
