Doc Rivers is unclear about the severity of Seth Curry's foot injury as the Philadelphia 76ers' availability concerns got worse with the guard withdrawn prior to Tuesday's 118-109 loss to the Milwaukee Bucks.

The 76ers went into the game leading the Eastern Conference at 8-3 despite being without Joel Embiid, Matisse Thybulle, Isaiah Joe and Tobias Harris due to COVID-19, with Ben Simmons also still unavailable.

Curry was pulled out of the 76ers side for the game shortly before tipoff with a left foot contusion.

"I don’t know," Rivers told reporters about Curry's injury after the game. "I literally thought he was gonna play and then late, you could hear the language, it didn’t sound like he was gonna play.

"We start adjusting pretty quickly after that. I’m not even sure what it is. I think it’s his toe, but I’m not sure."

Guard Tyrese Maxey scored 31 points, with five rebounds and four assists, while center Andre Drummond had 17 points along with 20 rebounds, but the 76ers missed their stars.

Rivers had indicated pre-game that Harris may be the closest to returning of the quartet who had entered the league's health and safety protocol.

"All the other guys are still where they're at. I would say just talking to Tobias, he's the one guy who'll be back sooner than later," Rivers said.

Rivers was impressed that the decimated 76ers, who also lost to the New York Knicks on Monday, were in the hunt against the reigning champions before a 27-16 fourth quarter.

"We gave ourselves a chance to win the game in both and there’s something to be taken from that so we do learn a lot," Rivers said. "But we didn’t win the games. That’s a fact.

"We had chances. It’s an opportunity to grow, an opportunity to get better, I’m not down about the loss. You either do one of two things in a competition. You either win the game or you lose the game. Period.”
