Memphis Grizzlies coach David Fizdale calls to players during the first half of the team's NBA basketball game against the Golden State Warriors on Saturday, Oct. 21, 2017, in Memphis, Tenn.

"Coach Fizdale worked tirelessly to achieve on-court success, and for that, we are grateful".

J.B. Bickerstaff is set to take over Fizdale's role for the meantime as coach of the Grizzlies, who are set to play Popovich's Spurs this Wednesday in San Antonio. Fizdale finishes his tenure in Memphis with a record of 50-51 over one-plus seasons. After jumping out to a 5-1 start this season, the Grizzlies have lost 11 of 13 games and are still without star point guard Mike Conley (heel). "We wish him and his family all the best in the future", Grizzlies Controlling Owner Robert J. Pera said via the team's official website.

The Grizzlies move prompted James and other National Basketball Association players and analysts to scoff on Twitter.

"I need some answers".

As news of Memphis Grizzlies coach David Fizdale's firing reverberated throughout the National Basketball Association landscape, league voices such as LeBron James and Dwyane Wade to the opportunity to speak out on the move.

"David Fizdale firing was so stunning I had to check, double-check & triple-check Woj's Twitter account to make sure it was legit", Michael Lee of "The Vertical" wrote. "Feels like my man was a fall guy". Things had to have deteriorated quickly for this to be the move the Grizzlies made, and I can not yet say that I understand why it was necessary.

The Grizzlies look to move forward with Bickerstaff, who joined the team as an associate coach in June 2016. Bickerstaff was most recently the interim head coach for the Houston Rockets, and is a highly-regarded coaching prospect himself.
