May 5, 2001 to July 11, 2026
South African footballer Jayden Adams was 25 when he died in July 2026. The midfielder had only recently represented South Africa at the 2026 FIFA World Cup, making his death particularly striking because he had just appeared on one of football's biggest stages.
Adams played all three of South Africa's group matches at the tournament. He had also helped Mamelodi Sundowns win the CAF Champions League and the domestic Betway Premiership after joining the club from Stellenbosch FC in 2025.
Adams' death was confirmed at 25, while no official cause was released.
2. Rondale Moore, 25

Former NFL wide receiver Rondale Moore also died at 25, making him the youngest American football player in this ranking.
Moore became a college football sensation at Purdue, where he earned consensus All-American honours as a freshman in 2018. He caught 114 passes for 1,258 yards and 12 touchdowns that season and became the first Big Ten true freshman to earn consensus All-America recognition.
The Arizona Cardinals selected him 49th overall in the 2021 NFL Draft. He later played for Arizona and Atlanta and signed with Minnesota. Moore's death was reported at 25, while authorities said the circumstances remained under investigation at the time.

September 19, 1996 to May 11, 2026
Memphis Grizzlies forward Brandon Clarke died at 29 after a seven-year NBA career spent entirely with Memphis.
The former Gonzaga standout was selected in the first round of the 2019 NBA Draft and became an important member of several Grizzlies playoff teams. He appeared in 309 NBA games, averaging 10.2 points and 5.5 rebounds.
The Los Angeles County Department of Medical Examiner later determined that Clarke's death resulted from the effects of heroin and cocaine and classified the manner of death as accidental.
4. Terrance Gore, 34

June 8, 1991 to February 6, 2026
Terrance Gore built one of the most unusual careers in modern Major League Baseball. He appeared in only 112 regular-season games, but his speed made him a valuable postseason weapon.
Gore was part of three World Series championship teams: the 2015 Kansas City Royals, 2020 Los Angeles Dodgers and 2021 Atlanta Braves.
His career is a reminder that impact in professional sport is not always measured by volume of appearances or traditional statistics.
5. Allan Nascimento, 34

September 11, 1991 to August 3, 2026
Brazilian mixed martial artist Allan Nascimento died at 34. The UFC confirmed that the flyweight was found unresponsive after an apparent heart attack while sleeping.
Nascimento competed six times inside the UFC Octagon and finished his overall professional career with a 22-7 record, including 16 wins by submission. His UFC record was 4-2.
He was also part of the Chute Boxe Diego Lima team and was closely associated with fellow Brazilian fighter Charles Oliveira.

Mauro appeared in 80 NFL games, starting 40, and recorded five career sacks. The Cardinals, Raiders, and Mauro's family confirmed his death, while no cause was publicly given in the NFL's report.

NASCAR star Kyle Busch died at 41, bringing one of the sport's most decorated careers to an unexpected end.
Busch won the NASCAR Cup Series championship twice, in 2015 and 2019, and finished his career with 63 Cup Series victories. NASCAR confirmed that he died after being hospitalised with a severe illness. His family later said severe pneumonia progressed into sepsis and caused rapid complications.
