Nickelback, who were named Billboard's 'Group of Decade' and kicked off 2010 by performing at the Closing Ceremony of the 2010 Winter Olympics, are showing absolutely no signs of slowing down. They have extended their Dark Horse World Tour. The next leg of the tour, produced by Live Nation, will begin on September 14 in Nashville and will run through October 30 in Las Vegas. Three Days Grace and Buckcherry will join Nickelback on these dates.

?The Dark Horse World Tour? has been a smashing success, as all previous legs have been completely sold out. Since 2009, Nickelback have sold more than 1.6 million tickets and have played more than 120 global shows.  

"Our fans have been amazing all over the world from Japan to New Zealand, Australia, Dubai, the UK and North America," said Nickelback's Chad Kroeger.  "Our fans keep us going and we are excited to play 25 more dates in the US with Three Days Grace and Buckcherry."
