The Celtics and Kristaps Porzingis are finalizing a two-year extension worth $60 million that would keep the 7-foot-3 big man in Boston through the 2025-26 season, according to a report Friday from TNT’s Chris Haynes.

The Celtics – who acquired Porzingis in the three-team deal that sent Marcus Smart to the Grizzlies last week – are eligible to offer their new addition a two-year extension up to $77 million beginning on July 6. So this deal – if finalized – represents something of a discount as the two sides clearly wanted to get something done to keep Porzingis in Boston as part of the Celtics’ core for the foreseeable future.

Porzingis opted into his $36 million player option for this season prior to being traded and the extension would start for the 2024-25 season.

“The idea of being here for a long time would be what I want,” Porzingis said in an interview with NBC Sports Boston this week. “It would be what I want and when the time comes, it’s hopefully going to be a discussion and we’ll see.”

If the Celtics agree to a supermax contract extension with Jaylen Brown – which is expected – they would be committing more than $100 million to Tatum, Brown and Porzingis in 2024-25.

“Obviously we really like Kristaps,” Celtics president of basketball operations Brad Stevens said about a potential Porzingis extension on Thursday. “We want him here. We obviously have him next year and then hopefully beyond, but we’ll see about all that.”

There is certainly risk with giving Porzingis a contract extension now since he hasn’t played a minute with the Celtics yet and it’s uncertain if he’ll be a good fit with Tatum and Brown. He also hasn’t stayed healthy for most of his career. But after Porzingis produced a career-best season in 2022-23, it could benefit the Celtics to come to an agreement now rather than waiting until after next season, when he could command more money in unrestricted free agency if he has another big season.
