Ravens' Levine suffers concussion at Miami

MIAMI GARDENS, Fla. (AP) Dolphins safety Louis Delmas has been carted off the field with a right knee injury against the Ravens.

Delmas was hurt midway through the fourth quarter Sunday.

Ravens starting cornerback Anthony Levine left in the first quarter because of a concussion and was ruled out for the rest of the game. That injury was a blow to a pass defense that ranks next to last in the NFL.
