Sanu (coach's decision) is listed as inactive for Sunday's NFC Championship at the Rams, Nick Wagoner of ESPN.com reports.
Only four days removed from the 49ers activating him from injured reserve, Sanu will miss his 12th game in a row. It's unclear if his previously injured knee is to blame, but the team's receiving corps is mostly healthy, so he'll remain in street clothes Sunday. Behind San Francisco's top duo of Deebo Samuel and Brandon Aiyuk, Jauan Jennings, Trent Sherfield and Travis Benjamin are the other wideouts available to the offense.
