Overview

• First-round pick Mykel Williams earned initial starting snaps opposite Nick Bosa but missed Tuesday’s session with a minor ankle issue that the 49ers describe as noncritical.
• Fourth-round rookie C.J. West dominated one-on-ones during San Francisco’s first padded practice, consistently beating blockers with power and quick hands.
• Quarterback Brock Purdy shrugged off a rolled ankle in Tuesday’s live drills, finishing practice without seeking treatment and reinforcing his durability.
• Head coach Kyle Shanahan is holding off on final judgments for running back Jordan James and receiver Jordan Watkins until they can be fully evaluated in pads.
• In Arizona, first-rounder Darius Robinson has cemented a role in the Cardinals’ first-team defense, rotating between interior and edge alignments during live-contact work.
