Samuel (groin) is listed as questionable for Sunday's game against the Bengals, Matt Barrows of The Athletic reports.
Coach Kyle Shanahan said Samuel did everything at Friday's practice, but given that it was a half-speed session the wideout was listed as a limited participant. A game-time decision is one of the possibilities ahead of Sunday's 4:25 p.m. ET kickoff, though it's also possible additional updates provide clarity before then. With RB Elijah Mitchell (knee/concussion) already ruled out, Samuel should get both carries and targets if he's able to play.
