Ravens backup outside linebacker Sergio Kindle suffered a left shoulder stinger during the second half of a 27-12 loss to the Detroit Lions on Friday night.
He 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 suffered another setback to his strained right calf.
After returning to practice this week, Reid aggravated the injury again for the third time since a June minicamp when he first hurt his leg 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."
Meanwhile, wide receiver LaQuan Williams and fullback Vonta Leach sustained sprained ankles and linebacker Ricky Brown has a hip contusion.
There were no apparent setbacks to previously injured players.
"The guys that had injuries go through well," Ravens coach John Harbaugh said. "So, that's good news."
