Cody has been dealing with a slight hip injury. He entered the game in the second quarter, but wasn't particularly active as he had one tackle.
Reserve running back Anthony Allen is proving to be a liability in pass protection.
Allen's suspect blocking allowed blitzing free safety John Wendling to sack quarterback Joe Flacco.
This marks the second week in a row that Allen has allowed a sack. Each time, he appeared to drop his head and failed to make solid contact.
Sergio Kindle suffers stinger, Jah Reid has setback
Ravens backup outside linebacker Sergio Kindle suffered a left shoulder stinger during the second half and didn't return.
"It wasn't good," Kindle said. "I don't know how to grade it, though. There were stinging sensations and pain. I feel better now. I don't think it's serious."
Meanwhile, offensive tackle Jah Reid acknowledged that he had another setback to his strained right calf.
After returning to practice this week, Reid aggravated the injury for the second time. He first got hurt during a June minicamp and was carted off the field.
"It's disappointing to not be out there helping the team," Reid said afterward in the locker room. "It's aggravated right now. We're working on it. Hopefully, I can be back soon. It's not as bad as the first two times I hurt it. It just takes time. I thought I was going to be able to play, but I need to make more progress."
Wide receiver LaQuan Williams and fullback Vonta Leach sprained ankles and linebacker Ricky Brown has a hip contusion.
There were no apparent setbacks to previously injured players.
"The guys that had the issues injury-wise got through well," Harbaugh said. "So, that's good news."
The Ravens also deactivated tight ends Ed Dickson (sprained right shoulder) and Dennis Pitta (broken right hand), defensive end Ryan McBean (broken left ankle ), wide receiver Devin Goda (undisclosed), linebackers Terrell Suggs (Achilles tendon), Josh Bynes (back) and Darryl Blackstock (groin, high ankle sprain) and wide receiver David Reed (ACL surgery).
Starting wide receiver Torrey Smith didn't play due to a sprained right ankle that has kept him out of practice, increasing playing time for young receivers LaQuan Williams and Tandon Doss.
Cornerback Jimmy Smith played significantly after dealing with a tight back throughout camp.
Smith was beaten for a touchdown by Lions wide receiver Calvin Johnson and seemed to have trouble moving smoothly throughout the first half.
Starting cornerback Lardarius Webb had forecasted an increased role for Smith this week after he didn't play against Atlanta, but Cary Williams got the start.
"He's coming along well," Webb said. "He's been a little short, but he is working his butt off, and that's something that we like to see from a young guy. He is coming out there as much as he can, and he's giving it all he's got."
