Celtics’ Kyrie Irving needs knee surgery, will miss playoffs

The Boston Celtics have spent most of the season adjusting on the fly. Now they will have to go through the 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.

Following 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 the player he was dealt for, Isaiah Thomas, is out for the year following hip surgery.

Irving 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.”

This latest news isn’t surprising considering the tight recovery window Irving faced. But it is a blow to a Celtics team that had been playing well despite a run of recent injuries to key players. Boston will likely enter the playoffs as the No. 2 seed behind Toronto.

In addition to Irving, Marcus Smart is sidelined following right thumb surgery and Daniel Theis is out for the season after left knee surgery. And Gordon Hayward is not expected back as he recovers from his gruesome ankle injury in the season opener.

While Toronto will most likely enter the postseason with the East’s top seed, the conference was still considered to be wide open prior to Irving’s injury.

With Irving out, the Celtics will now need someone to be the sparkplug for a team that had been hoping to make a run at the conference title following last year’s loss to Cleveland in the conference finals.

Boston certainly takes a hit without Irving, but it has been making adjustments to its rotation for weeks. Irving has been out for the last 11 games, with Boston going 7-4 without him.

The hole his absence created has been filled nicely by reserve Terry Rozier, who is playing his best basketball in his third year in the league. He has appeared in 77 of 78 games, starting 13. He’s made the most of his extra floor time, averaging 11.4 points, 4.6 rebounds and 2.8 assists — all career highs.

Others have stepped up as well.

Offseason pickup Marcus Morris averaged nearly 20 points a game last month and was key in Boston’s recent six-game win streak. Rookie Jayson Tatum has also hit a midseason stride, scoring in double figures in eight straight games before that streak ended in Wednesday’s loss at Toronto.

Veteran Al Horford and second-year forward Jaylen Brown have also had their moments over the second half of the season.

The question is whether a by-committee approach will be enough against potential first-round opponents, which could be Miami, Washington or Milwaukee.

Nowitzki has ankle surgery

Dirk Nowitzki’s 20th season is over a few games early after the Dallas Mavericks star had surgery on his left ankle.

Now the question is whether the 7-foot German will play as a 40-year-old after saying he intends to return for a 21st season, all with the Mavericks. Nowitzki could be the first to play that long with one franchise.

The team said Thursday that Nowitzki underwent a procedure to clear out unhealthy tissue, called surgical debridement. It was performed at a Dallas medical clinic.

Nowitzki, who turns 40 in June, played his final game of the season at home against Portland on Tuesday.

Lue to return Thursday night

Cavaliers coach Tyronn Lue says “piercing” chest pains persuaded him to take a medical leave.

He is returning to the sideline Thursday night after missing nine games. The 40-year-old coach says he’s feeling much better. He has changed his diet and says the time off has given him new perspective.

Lue hasn’t coached since March 17, when he left a game at halftime in Chicago because of chest pains.

The Cavaliers will be without point guards Jose Calderon and George Hill against Washington because of injuries. Calderon, who has given Cleveland a huge lift lately, is dealing with a sore left hamstring, while Hill will miss his third straight game with a sprained left ankle.

Etc.

The New Orleans Pelicans have brought back guard Jordan Crawford as the club tries to hang on to one of the final playoffs spots in the Western Conference. The Pelicans announced the move on Thursday, but terms of the deal have not been disclosed. The 6-foot-4 Crawford has played in 21 games for the Pelicans during parts of the past two seasons and has been a productive scorer in those outings, averaging 13.6 points.
