Stribling is considered day-to-day due to a shoulder injury, Matt Maiocco of NBC Sports Bay Area reports.
Stribling may have picked up the injury during the 49ers' 41-17 preseason win over the Chargers on Thursday, when he caught four passes on five targets for 46 yards. He's seen plenty of action over the Niners' first two exhibition games, so San Francisco could take the cautious route with the rookie second-rounder and hold him out of this Thursday's preseason finale against Las Vegas.
