The Warriors' forward was hurt late in the third quarter.
The Warriors went on to defeat the Rockets 104-99 to take a 3-2 series lead.
Durant left Wednesday's contest with a right calf strain which he suffered without receiving any contact. Yet with Durant ailing with a strained calf muscle, the Warriors haven't been stripped completely bare on the floor or, just as important, on their fingers, which are decorated with bling and the credibility that goes with it.
Steve Kerr won't have Kevin Durant, who - in Kerr's widely-shared opinion - "has been the best player in the National Basketball Association in these playoffs" for the rest of this series.
"A lot of it is factored into this spot in Game 6 where obviously Houston's backs are against the wall".
Warriors coach Steve Kerr and guard Stephen Curry noted that Durant was understandably down after the injury, but there was a palpable sense of relief within the locker room that his injury wasn't more severe.
While the Warriors survived Game 5 without their 7-foot offensive robot, Charles Barkley doesn't think they can do it again. James Harden scored 38 points to lead Houston to the win and Kevin Durant totaled 34 points in defeat for Golden State.
"Disappointed for him", Kerr said.
As we've detailed previously, Durant has had a version of this injury twice over the past two seasons, both times missing exactly seven days. Durant has served as a security blanket throughout these playoffs, while Curry and Thompson have struggled with their shot in this series, especially from 3-point range. Durant's status for the rest of the postseason - if Golden State beats the Rockets and heads to the conference finals - is up in the air.
Green, who grabbed 12 rebounds and dished 11 assists in Game 5, will be tasked with holding down the glass, protecting Golden State's backside defence and orchestrating offensive possessions. The team's diagnosis came early in the fourth quarter.
