Jim Otto, the legendary Pro Football Hall of Fame center affectionately known as "Mr. Raider," has died at the age of 86, the Las Vegas Raiders announced on Sunday. The cause of death has not been disclosed.

In a statement on social media platform X, the Raiders commemorated Otto as "The Original Raider," emphasizing his remarkable influence on both the American Football League (AFL) and professional football overall. Otto's career was marked by his relentless dedication and leadership, contributing significantly to the Raiders' dominance in the 1960s and 70s. Known for his exceptional work ethic, Otto managed to start an astounding 210 consecutive league games for the Oakland Raiders.

Despite being considered undersized when he graduated from the University of Miami, Otto handled the first snap in Raiders franchise history. He quickly established himself as a top player, being selected as the AFL's All-Star center every year throughout the league's existence. Otto is one of only 20 players who participated in every season of the AFL. His achievements include being named the starting center on the AFL All-Time Team and being selected to the NFL's 100th Anniversary Team in 2019. Otto was inducted into the Pro Football Hall of Fame in 1980, his first year of eligibility.

Throughout his career, Otto displayed incredible resilience, never missing a game due to injury. He played 210 consecutive regular-season games and 308 total games, even undergoing nine knee surgeries during his playing years. His health challenges continued post-retirement, with Otto undergoing approximately 50 surgeries, including multiple joint replacements. His right leg was amputated in 2007, and he faced additional health issues such as prostate cancer and severe infections.

Otto's career accolades are extensive: he was a 12-time Pro Bowler, a 10-time All-Pro, and an AFL champion. His final seasons were spent alongside fellow Hall of Famers Gene Upshaw and Art Shell, further cementing his legacy within the sport.

Following the news of his passing, tributes poured in from the football community. Raiders defensive end Maxx Crosby expressed his sorrow on X, stating, "Rip Jim Otto. Absolute Legend & Incredible Person."

Otto is survived by his wife Sally, his son Jim Jr., daughter-in-law Leah, and 14 grandchildren.
