Boston Celtics star Jayson Tatum was surprised upon learning the team owners' plans for the historic franchise in the coming years.

Mere weeks after capturing a record-breaking 18th NBA championship, Boston Basketball Partners LLC, the private investment group that owns the Celtics, announced it would sell all the team's shares.

Tatum opened up about the news to Sports Illustrated journalist Chris Mannix during his JT Elite Basketball Camp in Las Vegas.

The three-time All-NBA First Team member said he hopes the team's foundation and structure don't change under the next owner.

"What we've built, what we have, it's a great thing, and I don't want things to change," the 26-year-old added.

Boston Basketball Partners aims to sell a majority stake in 2024 or early 2025, with the remaining shares expected to be sold by 2028.

Celtics team governor Wyc Grousbeck will continue in his role until the entire transaction concludes in 2028.

Current Celtics co-owner wants to keep stake in the team

Meanwhile, Celtics co-owner Stephen Pagliuca plans to keep his stake in the league's most historic franchise.

"I hope to be part of the Celtics moving forward and will be a proud participant in the bidding process that has been announced today," the 69-year-old said in a statement.

Pagliuca currently serves as the team's managing general partner and executive committee member, being part of the group that bought the team for $360 million on the last day of 2002.
