Cleveland — LeBron James and the Cavs may have a conflict with the Biebs.

If Cleveland’s opening-round NBA playoff series against Detroit goes to five games, the April 26 game would bump a show planned by pop singer Justin Bieber at Quicken Loans Arena.

A sweep by the top-seeded Cavaliers over the eighth-seeded Pistons in the best-of-7 series would avoid any potential problem. However, Detroit beat Cleveland twice during the regular season so winning a game would be no surprise.

The Cavs are working with tour organizers to set up new dates for the Bieber show, if necessary.
