The Chargers are slated to waive Spiller, Ian Rapoport of NFL Network reports.
The 2022 fourth-rounder had been in contention with Kimani Vidal, Jaret Patterson and Elijah Dotson for a depth role in the backfield behind Gus Edwards and J.K. Dobbins, but Spiller is the odd man out ahead of Week 1. Once this week's cut-down dust settles, Spiller should either find his way on to another team's roster or end up with a practice squad slot.
