The Golden State Warriors have announced that head coach Steve Kerr is taking an indefinite leave of absence in a bid to recover from his back issues. The 50-year-old underwent two operations on his spine over the course of the summer, and supposedly he’s still having enough problems to limit his abilities as a coach. With the Warriors currently the reigning NBA champs supporters won’t want major upheaval before the start of the new season, but Luke Walton is to takeover in an interim capacity. In the NFL Baltimore Ravens wide receiver Breshad Perriman is out injured indefinitely having picked up another PCL complaint. It’s reported that Perriman sustained the injury during Sunday’s pregame warm-ups, and he’s now facing a long spell on the sidelines. Terrible news for the Ravens, of course, who are currently 1-4 for this season.
