Jalen Brunson refused to make excuses for the New York Knicks after injuries and fatigue hampered them in their Game 4 defeat to the Indiana Pacers on Sunday.

The Pacers recorded a dominant 121-89 win at Gainbridge Fieldhouse to level the teams' Eastern Conference semifinal series at 2-2, with Tyrese Haliburton scoring a team-high 20 points.

Haliburton was one of six Indiana players in double figures but it was their defense that did the hard yards, limiting Brunson to just 18 points in support of Alec Burks, who had 20 points of his own.

Brunson entered the contest averaging a league-high 34.6 points this postseason, but he was 6-of-17 shooting and received little support from elsewhere as Josh Hart had two points in 24 minutes and Donte DiVincenzo tallied seven.

The Knicks were sluggish from the off as they played a second straight game without defensive stopper OG Anunoby, who sustained a hamstring injury in Game 2.

Brunson, however, was not about to excuse their poor performance.

"We can talk about fresher legs and you can give us all the pity that we want," he said. "Yeah, we're shorthanded, but that doesn't matter right now. 

"We have what we have and we need to go forward with that. There is no excuse. There's no excuse whatsoever. If we lose, we lose. That's what that was."

The series will now head back to Madison Square Garden on Tuesday for Game 5, and Pacers coach Rick Carlisle expects a strong response from their opponents.

"New York is a team that has shown that it has an indomitable will to compete and rise above anything people say they can't do," Carlisle said. 

"We've seen it throughout the season. We've seen it in this series. We're believers in that, and so we've got to focus on us. 

"Everything is going to be a situation where you've got your hands completely full."
