Laremy Tunsil is inactive Sunday because of a shoulder injury, leaving the Miami Dolphins without three starting offensive linemen against the San Francisco 49ers.
Center Mike Pouncey was earlier ruled out due to a hip injury, and left tackle Branden Albert is out with a dislocated left wrist.
Anthony Steen is starting at center, Kraig Urbik at left guard and Sam Young at left tackle.
Pouncey and Albert both missed last week's game against the Rams, and Tunsil departed in the first half, leaving the Dolphins with a patchwork line as they earned their fifth victory in a row.
