It was only last week when promoter Live Nation, citing “production changes,” yanked the kick-off show originally scheduled for July 2 at the White River Amphitheatre in Auburn, Wash., moving opening night to the Fourth of July in Vancouver, B.C.

Now three more shows have dropped off the schedule. Gone is the July 15 gig at the Comfort Dental Amphitheatre located near Denver in Englewood, Colo. Also off the books are July 28 in Atlanta at Philips Arena and Aug. 3 near Indianapolis at the Verizon Wireless Music Center in Noblesville, Ind.

Although no reason has been given for nixing Noblesville and Atlanta, Live Nation posted a note on its website saying the Colorado date was dropped “due to a change in Rihanna’s schedule,” and that tickets would be refunded.
