Two of the Ravens' most promising defensive rookies suffered injuries Wednesday at training camp.
Defensive end Brent Urban, a fourth round draft pick out of Virginia, was carted off the field into the training room, unable to put weight on his right leg.
Urban has injured his right knee and will have a magnetic resonance imaging exam tonight to determine the severity of the damage. Urban had ankle surgery in February following the Senior Bowl, but had fully recovered from the procedure.
Ravens coach John Harbaugh said the team is a little more concerned about Urban.
"We're just hoping and praying for the best on that one," Harbaugh said. "It's his knee."
Meanwhile, second-round defensive tackle Timmy Jernigan limped into the training room under his own power. It's unclear what's wrong with Jernigan, but it didn't appear to be nearly as serious as what happened to Urban. Jernigan appeared to be favoring his back.
"Timmy looks fine," Harbaugh said.
Starting center Jeremy Zuttah was shaken up, but resumed practicing after being examined by trainers.
"Jeremy looks fine," Harbaugh said.
Jernigan has drawn heavy praise from defensive coordinator Dean Pees for his ability to disrupt plays. Jernigan was an All-American selection last season at Florida State before declaring early for the NFL draft.
