Kyle Shanahan provided an estimated injury timetable for key players who exited San Francisco's preseason tilt vs. the Las Vegas Raiders.

Injury updates from the preseason matchup between the San Francisco 49ers and Las Vegas Raiders at Allegiant Stadium in Las Vegas.

While it was positive to see 49ers quarterback Brock Purdy orchestrate a quick 12-play, 61-yard drive for points, San Francisco fans were naturally much more concerned with Puni's exit. Puni did jog off the field under his own power, but 49er fans will anxiously await a more thorough postgame update from San Francisco head coach Kyle Shanahan.
