CNN — (CNN) -- The Barenaked Ladies' show at SeaWorld has been taken off the theme park's concert schedule, a SeaWorld spokesman told CNN on Wednesday.
The decision to cancel the Canadian rock band's performance came two days after drummer Tyler Stewart posted a tweet saying the group is "looking at options" after viewing CNN's "Blackfish" documentary.
The documentary -- which aired on CNN last month -- tells the story of the SeaWorld trainer who was killed in 2010 by an orca named Tilikum.
Fans launched an online petition last week asking the group to cancel after the Barenaked Ladies announced it would perform at SeaWorld's Orlando park on February 15, 2014, during its "Bands, Brew & BBQ" events.
Mike Garrett of St. Catharines, Canada, posted the petition on Change.org asking band members to watch "Blackfish" and "learn how SeaWorld and other captive display facilities such as Marineland in Niagara Falls have for decades exploited marine mammals solely for profit."
Garrett said he was "disappointed" when he heard the group was scheduled to play there "in light of all the horrific information we're learning about places like SeaWorld and Marineland."
"I'm hoping to grab the band's attention on this issue and ask them, on behalf of all their animal-loving fans, to reconsider performing there," Garrett wrote. His petition had gained more than 9,200 signatures by Wednesday afternoon.
The petition drew Stewart's attention, who posted a tweet this week in response: "Like you, we've seen the movie and were affected. We're currently looking at options on how to proceed."
"Barenaked Ladies are not scheduled to perform at SeaWorld," SeaWorld spokesman Nick Gollattscheck said in an e-mail to CNN Wednesday. "They are not part of our concert line up."
The park's website does not list Barenaked Ladies on the schedule. February 15 and four other weekend dates just say "Coming Soon."
Acts that are listed on the calendar include Willie Nelson, Cheap Trick, REO Speedwagon, Martina McBride, 38 Special, Justin Moore and Scotty McCreery.
