As we previously reported, Justin's "Purpose" world tour was scheduled to touch down at the Quicken Loans Arena in Cleveland on April 26th ... the same night as Game 5 in the Cavs vs. Pistons series.
The two sides were scrambling to work out a plan -- (with the Bieber concert likely to get bumped to a later date) -- but to everyone's surprise, the Cavs SWEPT the Pistons in 4 games!!!
Translation -- the concert will go on as planned and everyone is happy!!
... except Detroit.
