Jacksonville reshapes its roster before the final week of the preseason, signing Jerome Carvin and Kevin Harris to add interior line and backfield depth while releasing Darrius Lassiter and Eli Mostaert, both undrafted rookies from 2025. Carvin, a 2023 undrafted center, slots in behind Fornter for camp depth, and Harris, a 2022 sixth-rounder with 16 rushing attempts, could offer a change-of-pace option behind starter Travis Etienne. In a separate move, the Jaguars acquired Khalen Saunders from New Orleans, adding interior run-stopping heft. These moves signal a shift toward bolstering depth and upside for late preseason reps and potential depth-chart bets as roster decisions loom.
