As noted, Brock Lesnar was recently added to the SmackDown live event at Madison Square Garden on Sunday, March 12th. The official website for Madison Square Garden revealed that Lesnar will face WWE Universal Championship Kevin Owens for the title at the event. Being that it is a SmackDown show, the match is being advertised as a "special attraction."
There is a possibility that Owens will not be Universal Champion heading into the match, as he is rumored to defend his title a week earlier at the WWE Fastlane pay-per-view on Sunday, March 5th.
