The Celtics announced Thursday that Daniel Theis underwent successful surgery to repair his left knee lateral meniscus.

"The surgery was performed by Celtics Team Physician Dr. Anthony Schena and was assisted by Dr. Paul Weitzel at New England Baptist Hospital. Theis is expected to miss the remainder of the 2017-18 NBA season but should be fully recovered prior to the start of training camp."

Theis sustained the injury during Sunday's loss to the Indiana Pacers.

Short-handed Celtics will need to find a way to get it done

BOSTON – As we hit this final stretch of the regular season, it’s not all that unusual to see some whacky lineups riddled with unproven, inexperienced players getting major burn while the team’s core players are on the bench.

The Boston Celtics are going to adapt a similar strategy, but not by choice.

We have seen them play short-handed before, but nothing like what we’ll see tonight when they host the Washington Wizards.


Gordon Hayward (dislocated left ankle) remains out. He’s joined by Kyrie Irving (left knee soreness), Marcus Smart (right thumb sprain) and Daniel Theis (left knee meniscal tear).

The one bright spot on the team’s injured list is Al Horford (illness) who did not play in Boston’s loss to Indiana on Monday but is listed as questionable for tonight’s game.

Having played short-handed all season, the Celtics have gone out of their way to not use players who are not available, as an excuse or justification.

And as decimated as their roster is heading into tonight’s game against the Wizards, that mantra remains alive and well.

“Continuing to be the next man up,” said Marcus Morris. “Guys that haven’t played this much throughout the year have an opportunity to go out and compete and be NBA players.”

Celtics rookie Semi Ojeleye will be among the Boston players whose playing time will see a spike in the coming days with so many players out with injuries.

“I’m just trying to be professional, staying ready whether you know if you’re playing or not,” Ojeleye told NBC Sports Boston. “Stay ready mentally, into the game. Everybody has done a great job of being ready when guys have been out all year.”

And it’s a trend that will be put to the ultimate test in the coming days.

Terry Rozier has been among the Celtics who have made the most of an increase role when given the opportunity to play.

In Rozier’s first career NBA start earlier this season when Irving was out with a right quad contusion, he tallied a triple-double of 17 points, 11 rebounds and 10 assists in Boston’s 103-73 win over the New York Knicks. He followed that performance up with a career-high 31 points and seven rebounds in his second start.

Aware that Irving will be out for a few games, the Celtics will certainly look to Irving to provide some offensive punch which will be needed if they are to improve upon their 5-2 record this season in games without Irving.

“I know it’s not easy,” Rozier said of playing without Irving. “You miss so much with him being out. All you can do is just try to make up for it when you can. We’re gonna need everybody to do that collectively.”

It's Greg Monroe's time to shine with Daniel Theis out for the season

BOSTON – The Boston Celtics had some options as the trade deadline drew near, but they seemed more enamored with the buyout market.

From the buyout pool, Boston could have pursued a wing scorer or a big man, both being well-established needs.

Boston went with a big man in signing Greg Monroe.


It was seen as a good move at the time, and even better now that Daniel Theis is out for the season after suffering a left meniscus tear in Boston’s 99-97 loss to Indiana on Sunday.

Many players, including Terry Rozier whose locker stall is next to Theis, said he didn’t find out about the injury until he arrived for practice on Monday.

“It sucks because that's my locker room guy. We're right next to each other at the arena and here so you know, we built a relationship,” Rozier said. “It's just tough to see it - not come to an end - obviously he's still going to be able to play basketball, but just with the season almost coming to an end, and then that happens, so it just sucks to see it. Great guy.”

But the injury to Theis reaffirms Boston deciding to acquire Monroe following him coming to terms on a buyout with the Phoenix Suns, rather than making a trade with the Memphis Grizzlies or the Los Angeles Clippers who wanted Boston to include a first round pick for any deal involving Grizzlies wing Tyreke Evans or Clippers guard Lou Williams who was a borderline all-star this season.

“One of the reasons why we wanted to sign Greg,” said Celtics coach Brad Stevens, “was because you never know what can happen with your depth inside.”

Indeed, adding Monroe provided Boston with added depth at the center position.

Prior to signing Monroe, the 6-10 Daniel Theis was the team’s only player off the bench they could turn to and get size.

But with Theis out, that depth won’t be nearly the same.

While Monroe is a much better inside, on-the-block scorer than Theis, Theis’ energy and hustle will be sorely missed.

“Just incredible reliability and energy,” said Celtics head coach Brad Stevens. “I appreciate the way he approached every day. And he’ll approach rehab the same way. You really feel for him. He was a guy that came in … he came in knowing he could play, but not even expecting him to have the kind of season he had. And he didn’t change that when we brought Greg in. We mixed up minutes here and there. He just kept being who he is. We’re going to miss him on the court. But he’ll have a full recovery and get back better than ever when he steps back on the court.”

There’s no telling what Theis’ absence will mean for Monroe who has appeared in 11 games for the Celtics, averaging 7.8 points and 5.0 rebounds while shooting 54 percent from the field.

But when he signed on with the Celtics over his hometown New Orleans Pelicans, it was an opportunity like the one before him now that Monroe has been waiting for patiently.

“I just try to be prepared for every game,” Monroe told NBC Sports Boston. “My perspective, my mentality, I try to go into every game with the same focus.”
