If Devon Kennard (hamstring) can't play Sunday, Herzlich could start at strong side linebacker.

Herzlich isn't the asset in pass coverage Kennard is, and on the strong side, his tackle upside is likely to be modest.

Herzlich suffered a concussion in Saturday's preseason game against the Jaguars, ESPN's Adam Schefter reports.

The special teams standout will immediately enter the concussion protocol, with its associated murky return timetable. Once he receives clearance, Herzlich will merely act as outside linebacker depth behind Devon Kennard and J.T. Thomas.

The Giants have re-signed Herzlich, nj.com reports.

Herzlich ended up starting eight games for the Giants in 2014 after Jacquian Williams was injured, recording 52 tackles and one sack in the process. This coming season, look for Herzlich to continue to provide the Giants with depth at linebacker, as help out on special teams.

With Jon Beason went down, Herzlich saw snaps at middle linebacker Sunday.

Herzlich didn't acquit himself particularly well, and Jameel McClain is more likely to inherit Beason's role for now.

Giants re-signed LB Mark Herzlich.

A former UDFA out of Boston College, Herzlich opened last season playing significant snaps at middle and strong-side linebacker, but was eventually weeded out in favor of more skilled players. He did rack up ten special teams tackles, which is really where 26-year-old Herzlich's strength lies in the NFL.

Mark Herzlich will take over as the Giants' starting middle linebacker.

Herzlich lost the job to Dan Connor during the preseason, but Conner has since landed on I.R. The Giants don't use their middle linebacker as an every-down player, severely capping Herzlich's IDP upside. For instance, Herzlich may only play 30 percent of the snaps in Sunday's game against three-receiver heavy Denver. WLB Spencer Paysinger will be New York's defensive playcaller.

The Giants released their first unofficial depth chart Thursday, and listed Mark Herzlich (MLB), Keith Rivers (SLB), and Spencer Paysinger (WLB) as starters.

The Giants have a nice group of linebackers in camp -- including Dan Connor, Aaron Curry, and Jacquian Williams -- but the trio of Herzlich, Paysinger, and Rivers are expected to open the season as starters. None of the three have a ton of IDP value because they'll be rotated too often.

Mark Herzlich will open training camp as the Giants' starting middle linebacker.

Herzlich lined up with the first-team defense during OTAs and minicamp. He remains the favorite to start, with Dan Connor likely to see playing time in sub-packages. "He has been very commanding," DC Perry Fewell said. "He's taken a leadership role out there and I think he has some respect from his teammates. Obviously, we want to find out what happens when the pads come on."

Mark Herzlich has continued to work as the Giants' first-team middle linebacker at OTAs.

It's unclear whether the Giants have designs on using Herzlich in sub-packages, but he could offer quite a bit of IDP upside if they do. He's likely competing for that role. The other tentative Giants starters are Keith Rivers (strong side) and Jacquian Williams (weak side), with Spencer Paysinger competing.

Giants LB Mark Herzlich lined up as the first-team middle linebacker at OTAs Wednesday.

Herzlich and Dan Connor are expected to compete for the spot this summer. Either one would be an upgrade on since-departed Chase Blackburn. Herzlich was flanked by Spencer Paysinger and Keith Rivers at outside 'backer.

ESPN New York expects Mark Herzlich and Dan Connor to compete for the Giants' starting middle linebacker job.

An early-round draft pick could also enter the mix. The Giants finished No. 25 against the run last season, and Herzlich or Connor would be an upgrade over since-departed Chase Blackburn. Connor graded out positively in run defense as the Panthers' starting MIKE 'backer in 2011, per Pro Football Focus.

Mark Herzlich is expected to start at middle linebacker in Sunday's game against the Steelers.

Normal starter Chase Blackburn is battling a hamstring injury. It's another chance for Herzlich, who started two games last season but lost his job after he sustained a high-ankle sprain. The inspirational cancer survivor has never recorded more than four tackles in an NFL game.

Mark Herzlich expects to compete for the Giants' starting middle linebacker job this year.

Herzlich started two games in the middle before an ankle injured ended his season in Week 12. The Giants have since re-signed Chase Blackburn and have also talked about moving Michael Boley to the middle. The odds are now stacked against Herzlich emerging as the starter.

Giants LB Mark Herzlich (ankle) returned to the practice field Wednesday for the first time since late November.

Giants LB Mark Herzlich (ankle) has been ruled out for Week 13.

Michael Boley (hamstring) is practicing this week, so Herzlich would have headed back to a special teams role had he been healthy. He's in a walking boot, a sign that his condition is week-to-week.

Giants LB Mark Herzlich left Monday's game during the second half with an ankle injury and did not return.

Herzlich said after the game that he believes he's fine, and his X-rays came back negative so we're optimistic he'll suit up next week. Herzlich was covering for injured Michael Boley (hamstring), and after getting gashed for 49 points by the Saints the Giants will need all hands on deck.

Mark Herzlich is expect to get his first start of the season in Week 11 against the Eagles.

According to the Newark Star-Ledger, undrafted rookie LB Mark Herzlich "hasn't had the sharpest of camps" with the Giants.

Star-Ledger reporter Mike Garafolo acknowledges that Herzlich had a couple of nice plays on Friday, but it sounds like he isn't headed for a roster spot. Herzlich didn't pick the best landing spot, as the Giants are deep at linebacker. If he's waived at final cuts, perhaps a needier team would take a flier.
