Jeff Tamarri, Longtime Indiana Referee, Collapses and Dies During High School Basketball Game in Monrovia

Jeff Tamarri, a longtime Indiana sports official known to generations of athletes as “Jeff the Ref,” collapsed and died Friday night while officiating a girls high school basketball game at Monrovia High School, authorities and school officials confirmed. He was 63.

Tamarri was working the varsity matchup between Speedway and Monrovia when he collapsed near the baseline with 6 minutes, 39 seconds remaining in the second quarter, according to witnesses. Athletic trainers immediately rushed to his aid and used a defibrillator as emergency medical personnel responded, but efforts to revive him were unsuccessful.

The game was halted, the gym was evacuated, and all remaining weekend games at the venue were postponed.

A Fixture in Indiana High School Sports

Tamarri, who lived in the Monrovia area, officiated basketball, baseball, and football across Indiana for decades. Friends and colleagues described him as fair, calm under pressure, and deeply respected by players, coaches, and fellow officials alike.

“He was so good about reading people,” said close friend and fellow official Terry Taylor. “He would get to know the kids on the field or on the court. The kids loved him. They always knew they could approach him.”

Taylor said Tamarri would have been most concerned about the players affected by the tragedy. “Jeff would apologize to the girls playing in the game tonight,” he said, holding back tears. “He would not want them to carry that burden.”

Emergency Response and Aftermath

Monrovia Athletic Director Jon Regashus, who previously officiated alongside Tamarri, said the referee appeared to lose his balance after stepping back into position following a rebound.

“I’m not a medical expert, but it appeared to be a cardiac arrest,” Regashus said. “It was awful. Just tragic.”

Regashus praised the response from trainers, emergency personnel, and both schools, noting that protocols were followed quickly and professionally. Saturday games at Monrovia were postponed out of respect.

Remembered as a Mentor and Friend

Beyond high school basketball, Tamarri umpired baseball and refereed football, mentoring younger officials and working countless youth and AAU games. He was especially well known in Zionsville youth football, where players greeted him with smiles, high-fives, and fist bumps.

Michael Pawlik, who entered officiating because of Tamarri, said his influence went far beyond rulebooks. “He was a top-notch official in every sport,” Pawlik said. “But the biggest thing was how much the kids loved him.”

Friends described Tamarri as fun-loving, passionate about officiating, and unwavering in his belief that “the kids come first.” No official cause of death has been released.

Tributes continued to pour in across social media Friday night as officials learned the news while working their own games — a reflection of the wide-reaching impact Tamarri had on Indiana’s sports community.

“He did it for all the right reasons,” said longtime friend Lance Scheib. “He made every game — whether third grade or high school varsity — about the kids. And that’s why he’ll be missed so deeply.”
