The 49ers will open the season against the Minnesota Vikings on Monday Night Football wearing alternate black uniforms.
The 49ers unveiled their new threads to the public in April.
Under NFL rules, teams are allowed to wear an alternate uniform up to two times per season.
San Francisco hasn’t changed jerseys since the 2009 season, and has never before worn alternates.
With the offseason departure of head coach Jim Harbaugh for Jim Tomsula, the alternate uniforms will ring in a new era in The Bay Area.
