COWBOYS 2013 INJURY UPDATE: Anthony Spencer knee surgery scheduled; young players get opportunity

Dallas Cowboys defensive end Anthony Spencer will require surgery on his left knee later this week.

An MRI confirmed a bone bruise after Spencer aggravated the knee during the team’s conditioning test Saturday. Spencer has been pained by the knee since the team’s OTAs in May and sat out the minicamp last month in hopes rest would heal it. But after this latest setback, doctors have advised minor surgery.

He is expected to be back in a few weeks, well in time for the season-opening game against the Giants. Spencer will miss valuable practice time as the Cowboys shift from a 3-4 defense to a 4-3 defense. Spencer and DeMarcus Ware are moving from outside linebacker to defensive end.

With DE Tyrone Crawford out for the season with a torn achilles, defensive tackle Jay Ratliff on the physically unable to perform list because a strained hamstring and defensive Anthony Spencer with a bone bruise, the Cowboys acknowledge a need for help and added numbers on the defensive line.

The Cowboys will scan the waiver wire for possible additions for depth purposes but they will look to the current players on the roster to step up and help fill the void. If they need to add a veteran like John Abraham or Richard Seymour, it will be at the end of the preseason, a source said.

“Injuries provide opportunity,” coach Jason Garrett said. “We have a lot of young guys who we like. Guys we want to see more of. This gives them a chance to show us what they can do.”

The Cowboys will look to guys like Cameron Sheffield to step up at end behind Spencer, DeMarcus Ware and Kyle Wilber and former Texas A&M tackle Ben Bass to fill the void inside. There is a chance Bass could get a look at end but the Cowboys are holding off on that right now.
