Health is of particular concern for Kyrie Irving, who following Sunday's game said that he's been dealing with pain in his left knee.
Indiana's Darren Collison had two points and 10 assists off the bench one game after returning from an 11-game absence while recovering from left knee surgery.
The Celtics would fall to the Pacers on Sunday night, with Irving only seeing the court for 16 minutes. It's likely that Irving, who suffered a broken knee cap in the NBA Finals back in 2015, will need to undergo a clean-up procedure on his knee this offseason.
Coming into this game, the Celtics were heavy favorites despite a report that Al Horford was not going to play because of sickness.
Marcus Morris drew an offensive foul on Oladipo during an inbounds play with 1.5 seconds left for a last-gasp chance, but Terry Rozier front-rimmed an off-balance shot, and the Pacers walked off as winners.
But the Celtics responded by scoring 7 straight to tie the game at 95 with 36 seconds to go.
Irving said the knee started bothering him during a March 3 showdown with the Houston Rockets, a game the Celtics lost 123-120.
"I think [rest] will probably be the best thing, just instead of kind of hoping it gets better over the two or three days that it usually does", Irving said, via ESPN . He sat out the team's win over the Chicago Bulls two days later before making his return in Thursday's win over the Minnesota Timberwolves. The team announced Daniel Theis will miss the rest of the season due to a torn meniscus, while Marcus Smart could miss time due to a thumb injury, per Wojnarowski.
Locked in at the No. 2 spot in the Eastern Conference, now is the time to give Irving the rest he needs.
Neither player can take over a game like Kyrie Irving can.
The Boston Celtics have had a continuous battle with the injury bug throughout the season. This news overshadowed the outcome of the game as the Celtics fell to the Pacers 99-97. We think it's general knee soreness, and he doesn't seem overly concerned big picture-wise with it.
Even without Irving and Jaylen Brown (concussion), the Celtics should have no problem defeating these cellar-dwellers.
"I'm not concerned. Where we are in the season, I'm pretty comfortable", he said. "Again, none of those things seem to be long term concerns, but we are going to make sure that obviously we're very alert".
