Samuel (quadriceps), who is listed as questionable, is trending toward a game-time decision for Sunday's matchup against the Dolphins, Jeremy Fowler of ESPN.com reports.
Samuel picked up a deep thigh bruise in last Sunday's win over the Saints, and the team has been relatively cautious with the star receiver's practice time as a result. The 49ers are expected to have Samuel test the quad injury in pregame warmups, but official word on his status may not arrive until San Francisco releases its inactive list 90 minutes prior to the 4:05 p.m ET kickoff.
