It's not a good day to be a Ravens rookie defensive lineman.

Via The Baltimore Sun, fourth-round draft pick Brent Urban had to be carted off of the practice field after sustaining a right leg injury. Urban is expected to compete for playing time in the Ravens' rotation at the five-technique position this season.

In addition, second-round pick Timmy Jernigan sustained an injury and limped off of the field with the help of a trainer. Jernigan has had a solid camp thus far and would be a blow to the Ravens if he's out for a while.

However, Jernigan's injury didn't appear as serious as Urban's.

Outside of Aaron Ross tearing his Achilles in the conditioning test, the Ravens had been major injury free until now. While Urban and Jernigan's status is yet to be determined, it's never a good sign when a player, in this case Urban, is being carted off due to a leg injury.
