The door isn't completely closed on Packers' Greer Martini

-- It's a dismal situation in the event of Jake Ryan's ACL injury last month and third-round pick Oren Burks' shoulder injury last week, but there are roster spots ripe for the taking at inside linebacker.

It's a prime opportunity for someone like Greer Martini, who has somewhat fallen behind the pack as he fights to secure his place in a Green Bay Packers uniform in 2018. The worst part is, he hasn't played terribly by any stretch of the imagination.

It's just that his counterpart, Ahmad Thomas, has played better.

Martini has recorded seven tackles -- three in two of the team's first three preseason games -- and shown the same quick agility he flashed at Notre Dame.

While with the Fighting Irish, Martini stepped into a full-time role for his junior and senior seasons, starting every game for those two years en route to compiling 130 tackles and three sacks.

The Packers snagged him as an undrafted free agent and have since not only implemented him into the defense, but he's also played extensively on special teams in the preseason.

That's likely Martini's best avenue to securing a roster spot -- finding a way to become multi-faceted and contributing in different ways.

"I think it’s always about the impression," said Martini after Tuesday's closed practice. Thursday night -- the Packers' preseason finale against the Kansas City Chiefs -- provides him one last chance to show what he's capable of in live action.

"This is the last impression I can leave on them, so obviously it’s the most important."

When on defense, Martini is a thumper in run coverage, which Ryan originally excelled at in 2017. That production may be significantly lacking, and the Packers may have recently acquired Antonio Morrison from the Indianapolis Colts in a trade over the weekend in an effort to shore up their run defense, but there's always room on the roster for gritty players like Martini.

"It’s just one of those things where I can’t really control the ultimate outcome. I can help the decision process, but for me, it’s just about doing what I can do, and that’s what I’ve been saying recently; just control the things that I can control. … It’s just about going out there and showing them one last time that I can do it at this level."

Thursday night will be reserved for the Packers' backups, meaning Martini should see a good portion of playing time. Almost an ideal scenario for someone clinging to the depth chart, which, the same case could be made for any bottom-of-the-barrel player doing all he can to make some noise before final roster cut-downs.

But this is nothing new for Martini.

"I’ve always worked my way into a position. Even when I wasn’t the most talented guy, I’ve always done the hardest stuff, I’ve always done the little things. It’s always ended up pretty good for me."
