Andrew Luck, former Indianapolis Colts quarterback, throws to former Stanford teammate Zach Ertz

Andrew Luck still knows how to pass.

>Stanford football posted video on Aug. 4 of the former Indianapolis Colts quarterback throwing to tight end Zach Ertz, a teammate with the Cardinal who is trying to return from the field after suffering an ACL injury late in the 2025 NFL season.

>Though Luck still slings it at 36 years old, he hasn't played since 2018 and is entrenched as Stanford football's general manager.

>Luck was Stanford's quarterback from 2009-11, twice finishing second in the Heisman Trophy voting before the Colts selected him first overall in the 2012 NFL Draft. Luck played six seasons for the Colts, passing for 171 touchdowns with 20 game-winning drives.

>The 35-year-old Ertz played at Stanford from 2010-12 and is a 13-year NFL veteran, the last two with the Washington Commanders, but is currently a free agent.
