If the Baltimore Ravens have major concerns about quarterback Joe Flacco's back injury, they're not letting on to them.
"We found out yesterday -- I guess it's something that's been bothering him for a week or two," head coach John Harbaugh said. "He didn't say anything about it. It wasn't really that bad; it flared up a little bit. [He] went and saw the back specialist, they're recommending about a week of rest. They say that should take care of it."
That said, Harbaugh said he wouldn't rule out bringing in controversial former San Francisco 49ers quarterback Colin Kaepernick.
