Kyrie Irving will undergo further tests on the ankle injury he suffered in the Brooklyn Nets' defeat to the Milwaukee Bucks on Sunday – a result that leaves the NBA playoff series all tied up at 2-2.
Irving twisted his right ankle after coming down on Giannis Antetokounmpo's foot after scoring from close range in the second quarter of Game 4 in the Eastern Conference semi-finals.
The seven-time All-Star received treatment on the court before walking to the locker room. The Nets later ruled him out for the remainder of the contest, though head coach Steve Nash confirmed after the game that X-rays on the issue came back negative.
"I have no idea what is going to happen with Ky in the coming days," Nash said.
"We will cross our fingers and hope that it is better than I don't know – better than what – better than missing the next game?"
Already without James Harden, Brooklyn slipped to a 107-96 defeat on the road. They host Game 3 on Tuesday, having recorded both their wins at home at the start of the best-of-seven series.
Irving had 11 points, five rebounds and two assists in 17 minutes of action.
Kevin Durant led the way for the Nets with 28 points but was stifled by the Bucks' physical defensive play which, at times, Nash felt went a step too far.
"[Tucker's] playing extremely physical. And made it difficult. That's his role on their team," Nash said. "I thought it was borderline non-basketball physical at times. But that's the playoffs."
Harden has not featured since suffering a hamstring injury in the early stages of Game 1. It remains unclear when the former MVP will return, though there are positive signs in his recovery.
"I asked him and he says he's feeling better, doing better," Nash said. "I asked the staff, they say, 'Yeah, it's getting better'.
"I think he's in that arena where he's got a little gap to make up. But he's getting closer, so it's been positive."
Antetokounmpo's 34-point haul helped Milwaukee make it two wins from two at home. He was helped out by 19 points from Khris Middleton, while P.J. Tucker added 13 to go along with his defensive work when tasked with slowing down Durant.
"We're very happy, but we've got to keep getting better, keep playing together and hopefully we can go into Brooklyn and take one," Antetokounmpo said.
Bucks head coach Mike Budenholzer added: "At this stage, it's whatever it takes to win the game.
"It certainly helps to get more guys contributing, making shots. P.J. Tucker was phenomenal on both ends of the court."
