Chargers bolster depth on the offensive line and at cornerback, signing Michael Dunn and Isas Waxter to the practice squad while releasing Myles Purchase and Rashad Weaver. Dunn, with Browns ties, adds interior protection and could push Foster Sarell into an active role if Joe Alt misses time. With Khalil Mack out and Tuipulotu flashing, Los Angeles is balancing pass rush and protection, keeping Justin Herbert protected as the roster reshapes.
