Ravens rookie defensive tackle Terrence Cody finally passed his conditioning test Wednesday and took part in practice. Cody, a 350-pounder out of Alabama, twice failed the test Tuesday. The drill consists of running 25 yards, doubling back, resting for 70 seconds and repeating it twice. "It's down and back, down and back, down and back. It's not complicated [but] it's a tough test," Ravens coach John Harbaugh said. "You've got to go out there and compete."
