The 49ers and Tampa Bay Buccaneers will be without their top running backs on Sunday when the teams meet at Levi’s Stadium in Santa Clara.

The 49ers on Friday officially ruled out running back Carlos Hyde from participating in the game due to a right shoulder injury he sustained in the 49ers’ 45-16 loss to the Buffalo Bills. The Buccaneers also announced running back Doug Martin would be unavailable because of a hamstring injury.

Hyde leads the 49ers with 429 yards and six touchdowns on 109 rushing attempts. Mike Davis and Shaun Draughn are expected to fill in for Hyde. The club is also expected to promote DuJuan Harris from the practice squad to be available.

Cornerback Rashard Robinson is listed as questionable, along with wide receiver Torrey Smith (back) and defensive tackle Glenn Dorsey (knee). Robinson continues to go through the league’s concussion return-to-play protocol.

Cornerback Jimmie Ward has been cleared for action. He is expected to return after a three-week absence due to a right quadriceps strain.
