Ravens wide receiver Derrick Mason was helped off the field late in this morning's practice after being hit by safety Dawan Landry.
With his arms draped over trainers' shoulders, Mason couldn't put any weight on his right leg.
"I just twisted it," Mason told reporters as he walked to the locker room, not specifying if he twisted his ankle or knee.
Ravens coach John Harbaugh indicates Mason has a sprained ankle.
Although just a sprain, Mason has seen his share of bumps and bruises over his vast career. He will need time depending on the grade of the sprain.
