Kyrie Irving and Gordon Hayward are expected to join their Boston Celtics' teammates in informal workouts in advance of training camp.

Irving and Hayward have been rehabbing this summer from follow-up procedures on their injuries.

Danny Ainge told ESPN on Monday that both Irving (knee) and Hayward (ankle) appear at full health and are ready for the new season.

"I don't want to hype it up too much, but I'm saying that if our training camp were starting today that they would be here today going full speed," Ainge said. "It's not like they need an extra month. I think that they know they have an extra month, so they are sort of pacing themselves. They're playing as if to build up to that opening day of training camp [Sept. 26]."

The Celtics were one win away from The Finals without Irving and Hayward.

"They'll both be here within the next week or so; by the time Labor Day is over, they will all be playing 5-on-5," Ainge said of Irving and Hayward. "I think it's just a matter of, if they're not playing 5-on-5 now, then it's only because they want it more of a controlled environment, I guess. They're doing everything -- dunking the basketball off both legs and playing one-on-one live and jumping and cutting and defending. I'm excited for them."

Michael Porter Jr. says he's free of pain after a second surgery on his back. Porter hopes to be on the court near the start of the 18-19 season.

"I finally feel, like, good," Porter said.

"I don't have a date but I'm hoping to be back for the beginning of the year. Gotta heal up, but I feel great," said Porter. "I'm able to get on the court a little bit right now, do something different things. But my rehab has definitely been very conservative. They're really taking it easy with me, being patient with me."

Porter underwent a microdiscectomy in November 2017 that repaired one of two bulging discs in his back. He underwent a second spinal surgery in July.

Jevon Carter suffered a torn right thumb ligament while participating in a skills camp run by legendary player development coach Tim Grgurich.

Carter was the No. 32 overall pick in the 2018 NBA Draft out of West Virginia by the Memphis Grizzlies.

The injury will require surgery but the Grizzlies are confident of a full return.

The Grizzlies signed Carter to a multi-year deal last month.

Jon Leuer underwent successful surgery on Wednesday, August 8 in New York in relation to a right medial meniscus injury that occurred during an offseason workout earlier this week.

Leuer will begin the rehabilitation process immediately and his return to full basketball activity will be updated prior to the start of training camp.

Zhaire Smith has suffered a Jones fracture in his left foot and will undergo surgery.

Smith suffered the injury on Monday while training at Tim Grgurich’s developmental camp in Las Vegas.

Smith was the No. 16 overall pick in the 2018 NBA Draft out of Texas Tech.
