Golden State Warriors head coach Steve Kerr said star Stephen Curry "did not feel well" prior to the team's buzzer-beating loss to the Charlotte Hornets.
Curry was ruled out just moments before tip-off as the Warriors suffered a last-gasp 102-100 defeat against the Hornets on Saturday.
Two-time MVP Curry took part in the warm-up before he was replaced by Mychal Mulder in the starting five.
"Going through his usual warm-up routine, he just did not feel well at all," Kerr said post-game, discussing Curry's absence.
"And so he came back in, saw the Charlotte team doctor, went out tried to warm up and just wasn't feeling good.
"So we made the decision, the training staff and Steph and I, we all made the decision to not play him.
"We'll see how he's doing [Sunday] ... There were no [COVID-19] protocols in place. Just him feeling sick."
Curry is averaging 29.9 points, 6.2 assists and 5.4 rebounds per game for the Warriors (16-15) this season.
It remains to be seen whether Curry will feature against the New York Knicks on Tuesday, with Kerr adding: "Hopefully. We'll see how he's feeling the next couple of days."
"Our offense is based on Steph," Kerr said. "Obviously our pace, everything else. So it took us some time to get our feet on the ground but once we did I thought we really competed well and did everything necessary to win the game. We fought, we competed together."
