Packers injury report: Thin at linebacker

GREEN BAY, Wis. – The Green Bay Packers will start two backup linebackers on Sunday against the Baltimore Ravens.

With all the focus on the loss of starting outside linebacker Clay Matthews, who underwent surgery Monday on his broken right thumb and will miss “multiple weeks,” according to coach Mike McCarthy, the Packers also were forced to deal with another hamstring injury to starting inside linebacker Brad Jones.

The Packers ruled out Jones for Sunday’s game. Third-year pro Jamari Lattimore, a college defensive end who made the Packers as an undrafted free agent and outside linebacker, will make his first career start. He and Jones both moved from outside linebacker to the inside position before the 2012 season.

Lattimore was actually third on the depth chart last week but played 16 snaps in Sunday’s win over the Detroit Lions after Jones went down and his replacement, Robert Francois, sustained a season-ending torn Achilles tendon.

Jones, who was slowed by a hamstring injury during training camp, pulled the hamstring in his other leg against the Lions.

“I have no reason to believe it’s going to be very long based on the discussions [Tuesday] with our medical staff,” McCarthy said. “He will not be available this week, and hopefully we feel better about it next week.”

The Packers had only three outside linebackers available for Wednesday’s practice. In addition to Matthews, they also were without Andy Mulumba (ankle), who played 17 snaps against the Lions. Mike Neal and Nick Perry will start at the two outside spots against the Ravens.

Cornerback Casey Hayward, who appeared close to returning last week from a hamstring injury that has kept him out all season, may try to practice on Thursday, McCarthy said.

“He’s getting better; a little sore after what he went through last week,” McCarthy said. “We’ll see where he is tomorrow. This time last week, he was able to do some individual work on Thursday. So that's the hope.”
