Dave Portnoy trolls Kyrie Irving with clown shirt during Game 2 of NBA Finals

He was also seen standing and cheering in a photo posted by the Celtics on social media after Boston’s 105-98 win in Game 2.

Portnoy, who sat next to a mystery blonde, also shared that Barstool Sports is selling the “KI Clown Tee” for $32 in a post on X.

It came after he made waves on social media when he and Camryn D’Aloia were featured on the live broadcast during Game 4 of the Celtics-Heat first-round playoff series last month.

The Celtics also trolled Irving during his return to TD Garden on Sunday.

They featured a quote by Irving on the Jumbotron after Boston’s 107-89 rout of Dallas in Game 1, which read: “I thought it was gonna be a little louder in here.”

Celtics faithful didn’t give Irving a warm welcome in his return to TD Garden for the 2024 NBA Finals after his unceremonious exit in Boston.

Irving played for the Celtics for two seasons in 2017-18 and 2018-19 and didn’t deliver an 18th title to the franchise before he left for the Nets.

Many were upset with Irving for leaving Boston after he said he would re-sign with the team.

Irving made headlines on a number of occasions for his beef with Boston since then.

Irving burned sage on the court at TD Garden to “cleanse the energy” before a preseason game between the Nets and the Celtics in December 2020.

The next year, he appeared to stomp on the Celtics’ logo, Lucky the Leprechaun, at mid-court and wipe his foot across it after Game 4 of the Nets-Celtics first-round playoff series in May 2021.

The 2024 NBA Finals series between the Celtics and the Mavericks will continue with Game 3 at American Airlines Arena in Dallas on Wednesday.
