Former Celtics guard Terry Rozier is under federal investigation in connection with an illegal betting scheme, The Wall Street Journal reported Thursday.

Investigators reportedly are seeking to determine whether Rozier, who currently plays for the Miami Heat, intentionally manipulated his performance during a March 23, 2023 game to help betters cash “under” prop bets placed on him. The same broader investigation resulted in former Toronto Raptors forward Jontay Porter’s lifetime ban from the NBA.

“Authorities believe some of the people who arranged for Porter to fix his performance in two games last season had inside information that prompted them to bet large sums of money against Rozier a year earlier,” The Wall Street Journal’s Jared Diamond, Louise Radnofsky and Robert O’Connell wrote.

In the game in question, Rozier, then a starter for the Charlotte Hornets, played nine minutes against the New Orleans Pelicans before exiting with a foot injury. He finished with five points, four rebounds, two assists and one steal in a 115-96 Hornets loss, then did not play again for the remainder of the 2022-23 season.

Wagers placed on Rozier earlier that day reportedly aroused the suspicion of watchdog gambling firm U.S. Integrity, which notified the NBA and sportsbooks “that unusual wagers were coming in on Rozier failing to meet certain statistical benchmarks, such as the total number of points or rebounds he would record in the game.”

In a statement to The Wall Street Journal, NBA spokesman Mike Bass said the league conducted its own investigation into the matter and found no wrongdoing by Rozier.

“In March 2023, the NBA was alerted to unusual betting activity related to Terry Rozier’s performance in a game between Charlotte and New Orleans,” Bass said. “The league conducted an investigation and did not find a violation of NBA rules. We are now aware of an investigation by the U.S. Attorney’s Office for the Eastern District of New York related to this matter and have been cooperating with that investigation.”

Jim Trusty, an attorney for Rozier, told The Wall Street Journal he is “confident that the ongoing government investigation will arrive at the exact same conclusion” as the NBA’s.

Unlike Porter, a fringe NBA player who was on a two-way contract when his lifetime ban was handed down last year, Rozier is an established NBA veteran, appearing in 643 career games with 379 starts over his 11 pro seasons. Drafted 16th overall by Boston in 2015, he was traded to Charlotte in 2019 and then to Miami last January.

Currently in Year 3 of a four-year, $96.3 million contract, Rozier has appeared in 42 games for the Heat this season, starting half of them and averaging 12.1 points, 4.1 rebounds and 2.8 assists per game. The 30-year-old averaged at least 18 points per game in each of his five seasons with the Hornets and was Charlotte’s leader in points (21.1) and assists (5.1) in 2022-23.
