Boston Celtics have spent most of the season adjusting on the fly and now they will have to go through the NBA playoffs without Kyrie Irving.
The star point guard will need surgery on his left knee and is done for season.
The team on Thursday put his recovery time at four to five months.
Irving hasn't played since March 11 and says he won't dwell on what might have been.
"The hardest thing to do sometimes is accept the uncontrollable things life throws at you," he wrote in an Instagram post.
"It's simply a test of your perseverance and will, to be present, even in the wake of what's going on."
In the upcoming surgery, two screws will be removed. They were implanted after Irving's patellar fracture during the 2015 NBA Finals.
Irving recently developed an infection at the site of the screws, and now they must be taken out.
After his original procedure last month, the team had said the knee was structurally sound and the kneecap healed, but the wire had been putting pressure on the knee.
This is Irving's first season in Boston, after he demanded to be traded from Cleveland, and he believes his best basketball is ahead of him.
"This season was only a snapshot of what's to come from me," he said in his post.
"Trust Me. The journey back to the top of Mt. Everest continues."
Boston, who have battled with iknjury problems all season, will likely enter the playoffs as the No.2 seed in the eastern conference.
In addition to Irving, Marcus Smart is sidelined after right thumb surgery, Daniel Theis is out for the season after left knee surgery and Gordon Hayward is not expected back as he recovers from his ankle and leg injury in the season opener.
