Evans (ribs) was a non-participant at Thursday's practice, Nick Wagoner of ESPN.com reports.
Evans thus will have just one more chance to mix into drills Friday before the 49ers potentially make a ruling on his status ahead of Sunday's game against the Broncos. If Evans ends up being inhibited or sidelined this weekend, Deebo Samuel and Brandin Cooks represent the notable names that remain healthy in San Francisco's WR corps.
