What losing Urban means to Ravens

The Baltimore Ravens' depth on the defensive line took a hit Thursday when it was announced that rookie defensive end Brent Urban is out for the season.

Urban, the team's fourth-round pick, tore the anterior cruciate ligament in his right knee Wednesday. The results of his MRI were what the Ravens had feared.

"It's a clean tear -- that's a positive," coach John Harbaugh said.

Losing Urban means the Ravens need a productive season from Kapron Lewis-Moore. Urban had expected to be the primary backup to Chris Canty, but that role now falls on Lewis-Moore.

A sixth-round pick from a year ago, Lewis-Moore missed his entire rookie season because of a torn ACL he suffered in his final game at Notre Dame. There has been increased buzz about Lewis-Moore this offseason and in camp.

Coming back from an injury is nothing new for Urban. He tore the ACL in his left knee five years ago, and he came back from offseason ankle surgery this year.

Here are the other injury updates from Harbaugh:

  • ILB Daryl Smith has a minor groin injury and hasn't practiced for the past two days. "We gave him a little time," Harbaugh said.

  • WR Jeremy Butler also has a groin injury and didn't practice.

  • DT Timmy Jernigan is suffering from back spasms after leaving the field Wednesday. "He'll be back soon," Harbaugh said.
