He was born in 2008 and has developed a strong interest in American football.

His football experiences have attracted increasing attention because he is following a family tradition that spans three generations.
Why Did Kyle Shanahan Name His Son Carter?
One of the most interesting details about Kyle Shanahan’s family involves the origin of Carter’s first name.
According to People magazine, the name was partly inspired by American rapper Lil Wayne, whose real name is Dwayne Michael Carter Jr.

He recorded two receptions as his team secured a 31-23 victory.
Several San Francisco 49ers players attended the game to support him, including Trent Williams, Christian McCaffrey, Kyle Juszczyk, George Kittle and Mac Jones.
The experience was particularly meaningful because Carter had previously served as a ball boy during 49ers training camps.

The moment highlighted the family’s multigenerational connection to the organization.
