Warriors' Walton says no prospective return date for Kerr, Bogut

The Golden State Warriors are not sure when their head coach and starting center will be back with the team. Interim coach Luke Walton said Monday that there is no time frame for the return of either Steve Kerr or Andrew Bogut to the defending NBA champions.

Kerr is still recuperating from offseason back surgery which was complicated by a spinal fluid leak. Discomfort forced the 2014-15 NBA Coach of the Year to step away from his duties following the opening two days of training camp.

Bogut, meanwhile, suffered a concussion on opening night against the New Orleans Pelicans and has not played since. The Dubs have started Festus Ezeli in his place and rode Stephen Curry's 39.3 points per game to a 3-0 record in the interim.

The Warriors host the Memphis Grizzlies on Monday night and visit rivals Los Angeles Clippers on Wednesday.
