Overview

• Brock Purdy and Christian McCaffrey have returned to full-contact drills, solidifying an offense keen to avoid last year’s injury-plagued season.
• Ongoing setbacks to Brandon Aiyuk, Jauan Jennings and Jacob Cowing have forced the 49ers to re-sign Equanimeous St. Brown and release Andy Isabella to bolster receiver depth.
• The team’s first unofficial depth chart names McCaffrey, Ricky Pearsall and George Kittle as starters, while rookie corner Upton Stout holds the early edge at nickel.
• Defensive coordinator Robert Saleh praised Mykel Williams and Alfred Collins for consistent growth, and ESPN spotlighted second-year corner Renardo Green as a defensive building block.
• As joint practices with the Broncos approach and the preseason opener looms this weekend, competition for roster spots and the kicking job is entering its final stretch.
