Kyrie Irving may have returned to the court Friday to help the Dallas Mavericks defeat top-seeded Oklahoma City, but his ongoing back injury will require rest in some instances. Irving missing Wednesday’s controversial loss to the New Orleans Pelicans was an example of him taking a night off to manage a bulging disc in his back.

Kyrie Irving — an expert in rivalries — agreed that the Thunder and Mavericks have become arch-nemesis. “It’s personal. I think it’s the start of a healthy rivalry," Irving said. "... We’re gonna be seeing them a lot over the next few years so it’s good that you set the precedent now what it’s gonna be like.

Irving is listed on the injury report as he continues to deal with a lumbar back sprain. Meanwhile, Dereck Lively II (right ankle sprain), Luka Doncic (left calf strain) and Dante Exum (right wrist surgery) are all out for Friday's game. It is worth noting that Mavs head coach Jason Kidd previously said he expects Irving to play on Friday.
