What happened: The Denver Broncos elevated defensive backs Brent Austin and Sean Fresch Jr. from the practice squad for Sunday's matchup against the Los Angeles Chargers. Both are rookies, with Austin entering from California and Fresch from Rice.

Why it matters: The roster additions offer necessary coverage following injuries to starting cornerbacks Pat Surtain II and Riley Moss against San Francisco. Austin and Fresch serve as emergency support behind Kris Abrams-Draine and Jahdae Barron.

What to watch: Denver navigates early-season AFC West division stakes while managing a depleted secondary.
