Former Auburn WR Duke Williams appears to have inspired a CFL rule change.

Williams, currently a wide receiver for the Edmonton Eskimos, caught a touchdown pass during a Canadian Football League game against the Montreal Alouettes on Saturday night. He decided to celebrate the scoring play by crawling through an advertising placard set up on the field, as shown in the clip below.

Unsurprisingly, the celebration earned him a penalty flag. But the league has decided it won’t lead to a flag any more. On Thursday, the CFL announced players will be allowed to use props in post-touchdown celebrations, but with limitations. The props cannot be hidden in the uniform or goal post, considered demeaning or discriminatory or be used to simulate the firing of a weapon.

“This change came after discussions held by the commissioner, presidents from the league’s member clubs and on-field officials and supervisors,” CFL director of officiating Darren Hackwood said. “Everyone involved wants to reach the right balance between giving players an opportunity to express their joy and creativity and maintaining the pace and sportsmanship of our game.”

Williams joined the Eskimos prior to the start of the 2017 season. In 2016 he signed as an undrafted free agent with the NFL’s Los Angeles Rams, but was cut from the roster before the ’16 season.
