Billy Ray Smith Jr., a prominent linebacker for the San Diego Chargers, has died at the age of 64. His family has stated that his battle with dementia was a result of chronic traumatic encephalopathy (CTE), a degenerative brain disease often linked to repeated head trauma experienced by football players.

"It is with profound sadness that we share the loss of our beloved Billy Ray Smith Jr., who passed away peacefully surrounded by family," the family said in a statement. "Billy Ray faced his long journey with dementia caused by CTE with unmatched bravery, dignity, and strength."

While the family attributes his dementia to CTE, it is not publicly clear if an official diagnosis was made. CTE can only be definitively diagnosed after death.

Smith played 10 seasons in the NFL, all with the Chargers. During his career, he recorded 26.5 sacks, 15 interceptions, and 13 forced fumbles in 126 games. He was later named to the Chargers' 50th Anniversary Team. His father, also named Billy Ray Smith, was an NFL linebacker who won a Super Bowl with the Baltimore Colts in 1971.

Smith's family noted his positive impact, stating, "Billy Ray brought so much joy, light, and laughter to the world as a devoted father, husband, son, and loyal friend." They added, "On the NFL gridiron for a decade with the Chargers, and decades that followed in sports broadcasting, Billy Ray earned deep respect from teammates, colleagues, and fans, who he cherished in return."

Smith later transitioned to sports broadcasting, working as a sportscaster at San Diego's KGTV. His wife, Kimberly, also worked as an anchor at the station. He is survived by his wife and their daughter, Savannah, born in 1992. The family expressed gratitude for the community's support during this time: "His undeniable legacy will live forever in our hearts, and we thank our incredible community for the outpouring of love and support."

The link between repeated head trauma in football and CTE has been a subject of increasing concern and research within the NFL community. The Boston University CTE Center suggests that the risk of developing the disease doubles for every 2.6 years spent playing the game. Other former NFL players, such as Hall of Famer Junior Seau, a former Chargers linebacker, were found to have CTE after their deaths. The family of former offensive lineman Jordan Devey also recently shared their belief that he suffered from CTE prior to his death, although his brain could not be studied due to the circumstances of his passing.
