Ravens rookie linebacker Sergio Kindle will miss all of training camp after fracturing his skull, coach John Harbaugh said Monday. Kindle suffered the injury while falling down two flights of stairs last week. "You're talking about a head injury playing football, that's not something we're not going to be in a hurry to mess with. From a football standpoint, we'll move on with the guys we've got, and we'll get ready to play the season," Harbaugh told reporters. Harbaugh wouldn't rule out Kindle playing for the Ravens this season. "We'll be preparing without Sergio. Then if at some point in time he can come back and play, that will be a bonus to us. But he'll have a lot of catching up to do," Harbaugh said.
