Blake Martinez gathered his fellow inside linebackers together after a tough day at Green Bay Packers practice.

It's difficult to see two key members of the defense go down with injuries on just the fourth day of training camp.

Inside linebacker Jake Ryan Saints Elite Jerseys , one of the team's top run defenders, was carted off the field late in practice Monday with an apparent right leg injury. Kentrell Brice, a potential starter at safety, was carted off the field during a special teams drill, though the type of injury was unclear.

"Oh Cheap John Franklin-Myers Jersey , man. That was bad, man. You hate to see that, especially as a player. That's your brother," safety Josh Jones said when asked about Brice.

Practice ended up being cut short early because of the threat of lightning. The injuries dampened the mood in the locker room.

Back inside Lambeau Field, Martinez gathered the rest of his position group together. Martinez (158) and Ryan (89) led the team in tackles last season.

After third-year pro Martinez and Ryan Adidas Drew Doughty Jersey , who is in his fourth year, rookies fill the inside linebacker depth chart. Martinez called a position meeting to get everyone refocused.

"It just comes down to 'What are we going to do now?'" Martinez said in recounting his message. "Or whatever your mindset is, what are you going to do to get better every day?"

Oren Burks, a third-round draft pick out of Vanderbilt, might play a bigger role if Ryan misses significant time. Burks played inside linebacker in college last season after taking on a hybrid linebacker/safety role as a junior. He played free safety as a sophomore.

The Packers are also making changes on defense after Mike Pettine replaced Dom Capers as coordinator. Martinez said that he'll be checking on the rookies constantly to make sure they are up to speed.

"I know my goals for this season Authentic Jonathan Allen Jersey , our team goals for this season and I'm not going to let one injury kind of ruin that for us," he said.

Brice appeared in line to take a starting job at safety following the offseason departure of veteran Morgan Burnett, who signed with the Pittsburgh Steelers as a free agent. Brice played six games with three starts last year before going on injured reserve with an ankle injury on Nov. 3. He played in all 16 games with one start as a rookie.

Coach Mike McCarthy likes Brice for his positional versatility, a trait that has become more important on defenses to help keep up with expanding passing attacks. The Packers are still deep at safety, where promising second-year player Jones might get more snaps if Brice misses a lot of time.

The defense must move on Cheap Marquis Haynes Jersey , as hard as that might be to do after a trying day.

"It's kind of tough. You just do it because it's part of your job. But in the back of your head, it's always there though," said cornerback Demetri Goodson, who came back from a serious knee injury earlier in his career.
