Terrelle Pryor has been confirmed as the starting quarterback for the Oakland Raiders on Sunday.
Leinart told The AP: "The competitor in me wants to play, wants to start, but I do understand that they need to evaluate him, and I get that.
"Obviously, you're not happy by any means, but at the same time, I'm a team player. I'm happy to help."
The Raiders face the San Diego Chargers tomorrow.
