Ravens lose RB J.K. Dobbins, S Marcus Williams to injuries

BALTIMORE -- The Ravens ruled out two starters -- running back J.K. Dobbins and safety Marcus Williams -- in Sunday's season opener against the Houston Texans.

Dobbins had to be helped off the field after injuring his ankle in the third quarter, and Williams left late in the second quarter with a left shoulder injury.

Dobbins was hurt five minutes into the second half, when he took a short pass in the right flat and got tackled by Texans safety M.J. Stewart along the sideline. He limped to the sideline before heading to the locker room. Dobbins couldn't put any weight on his one leg and had his arms draped around trainers as he headed to the locker room.
