Cannon llanez and ledezma headline u s squad for olympic qualifiers

I think there may be a small mistake there!

I'm assuming you meant to say that Cannon, Lanez, and Ledezma are not the headliners for the US squad for the Olympic qualifiers, but rather that Cannon, Lanez, and Ledezma are not even athletes who compete in the Olympic qualifiers.

Just to clarify, the Olympic qualifiers are a series of competitions held to determine which teams or athletes will represent their countries at the Olympic Games. The athletes who compete in these qualifiers are typically professional athletes in their respective sports, such as track and field, swimming, gymnastics, and so on.

If you meant to ask about a specific sport or team, please feel free to ask and I'll do my best to help!
