Mike Evans left San Francisco's 23-17 Monday night win over Washington early with Achilles soreness and didn't practice the rest of the week. The 49ers veteran's injury status heading into the next game remains unclear after he sat out Thursday, Friday and Saturday. Evans' absence from practice is a red flag for a receiving corps that can't afford depth losses as the season moves forward. The exact severity of the Achilles issue hasn't been detailed, but missing three straight practice days suggests San Francisco is being cautious with the injury rather than ruling him out entirely.
