The Ravens worked without two offensive starters, running back Willis McGahee and tackle Jared Gaither, for Sunday's morning practice.
After practice McGahee wouldn't reveal his injury but he indicated that it would be short term.
Gaither, who was injured in Saturday's workout, missed Sunday's practice with an injured right ankle.
Adam Terry continued to work at Gaither's left tackle spot, and Mike Kracalik ran with the starting offense at right tackle.
"He woke up and it was swollen," Ravens coach John Harbaugh said. "They’re evaluating it still."
Running backs P.J. Daniels (cramps) and Cory Ross (undisclosed) along with offensive lineman David Hale (undisclosed) did not practice.
