Duggan was waived by the Chargers on Monday, Tom Pelissero of NFL Network reports.
Duggan was selected in the seventh round by Los Angeles in the 2023 NFL Draft. After not making the team's initial 53-man roster, the TCU product spent the 2023 campaign on the team's practice squad. Duggan's departure leaves Easton Stick and Luis Perez behind starter Justin Herbert on the team's quarterback depth chart.
