Philadelphia 76ers guard Seth Curry returned a positive test for the coronavirus, which the team learned of near the start of its 122-109 loss to the Nets in Brooklyn on Thursday night, sources told ESPN.

The Sixers are staying overnight in New York and will commence contact tracing Friday morning, sources said. The team will do a new round of testing Friday in accordance with the league's health and safety protocols.

Curry, who sat out Thursday's game with left ankle soreness, spent the first quarter on the bench before the Sixers were made aware of a positive test, sources said. He was wearing a mask and was seated next to assistant coach Sam Cassell and center Joel Embiid.

Curry then left the court area and headed into isolation. He left the Barclays Center separate from the team.

Embiid, who has a 3-month-old son, told ESPN he plans to self-quarantine from his family until he is satisfied he didn't contract the virus.

Philadelphia is next scheduled to play Saturday at home against the Denver Nuggets.

Sixers coach Doc Rivers, who is Curry's father-in-law, said before Thursday's game that Curry had suffered the ankle injury late in Philadelphia's 141-136 victory over the Washington Wizards Wednesday night, in which Curry scored 28 points on 11-for-14 shooting 36 minutes.

Rivers said he had "no idea" when Curry suffered the injury. Shake Milton started in his place against the Nets.

"I know it was in the game [Wednesday] ... I think somewhere in the fourth quarter late," Rivers said. "But as far as how long he'll be out, my guess is day-to-day. I don't think it's a serious injury, but it's the right thing to do."

Curry appeared to be seated on the front row of the bench at the start of Thursday night's game, sitting next to Cassell and two seats away from backup center Dwight Howard, until the veteran big man laid on the baseline to stretch before entering the game.

When Embiid headed to the bench with 3:05 remaining in the first quarter, he sat in the seat directly to Curry's left, where he remained for the rest of the first quarter.

At the start of the second quarter, Embiid was still in his seat, and Cassell was still in his, but the seat Curry had occupied was empty. And it appeared to remain that way for the rest of the game.
