49ers training camp: Observations from July 25 practice

The San Francisco 49ers completed their third training camp practice on Friday, the second-to-last unpadded session to open camp. As usual, social media buzzed with real-time updates from reporters and local media, giving fans an inside look at the day's on-field action.

Quarterback Brock Purdy was excused from practice for personal reasons, opening the door for backups Mac Jones and Tanner Mordecai to take additional reps and showcase their abilities. Purdy is reportedly expected to return to practice on Sunday.

Wide receiver Jacob Cowing remains sidelined after suffering a hamstring injury on Wednesday. Additionally, multiple reporters noted that cornerback Renardo Green appeared to tweak his left leg during Friday's session—a situation worth monitoring as camp progresses.

"It looked like he was trying to stretch out his hamstring," Jennifer Lee Chan of NBC Sports Bay Area noted.

Here are the key practice updates as shared across social media.

After arguably his best practice with several past break ups #49ers CB Renardo Green came off the field a little gimpy. He took his helmet off, walked off the field and did not practice the rest of the session. It looked like he was trying to stretch out his hamstring.— Jennifer Lee Chan - also bluesky @jenniferleechan (@jenniferleechan) July 25, 2025

Ji'Ayir Brown intercepted Jones and broke down post-practice huddle
Mordecai also had a pass intercepted (Jalen Graham)

CB Renardo Green had multiple PBUs, appeared to tweak left leg on deep PBU from Jones to Jennings

Also, Lenoir had brief tussle with Jennings, no biggie

With Brock Purdy absent (personal/not cause for alarm), Mac Jones took the first- and second-team reps today. I had him at 12-19 and Tanner Mordecai 9-13. That's not counting probable sacks by Nick Bosa (v Colton McKivitz) and Bryce Huff (v Spencer Burford).— Matt Barrows (@mattbarrows) July 25, 2025
