Chung is ruled out for Sunday's game against the Jaguars due to a concussion, Zack Cox of NESN.com reports.

EDGE Analysis

Duron Harmon will replace Chung as New England's starting strong safety for the remainder of Sunday's game. The 31-year-old will look ahead to Week 3, and attempt to clear the league's concussion protocol in time to suit up for the Patriots' matchup against Detroit.

The extension Chung signed Saturday is worth two years and will keep him in New England through the 2020 season, Jeff Howe of the Boston Herald reports.

EDGE Analysis

Chung has been a mainstay in the Patriots secondary since New England selected him in the second round of the 2009 NFL Draft. He'll be 31 years old at the start of the 2018 campaign, but his advanced age is yet to show in the stat sheets considering he's averaged 86.3 tackles over the past four years while notching at least seven pass breakups in three of those four seasons. Chung will remain on the IDP radar so long as he holds his grip on his starting job throughout the remainder of the offseason.

Chung signed a contract extension with the Patriots on Saturday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Chung has been a staple of the New England secondary for the better part of a half decade now. Entering his 10th NFL season, it's reasonable to expect the safety's playing days are pivoting towards the end of the road. Chung has reached at least 84 tackles in each of the last four seasons with the Patriots.

Chung logged 63 of a possible 75 snaps on defense before exiting Sunday's 41-33 loss to the Eagles in Super Bowl LII due to a concussion.

EDGE Analysis

Prior to his exit, Chung recorded a team-high nine tackles (six solo). Chung, who finished the 2017 regular season with 84 tackles and a pick in 16 games, remains under contract with the Patriots in 2018. He's in line to remain a starting strong safety for the team next season, working in tandem with free safety Devin McCourty.

Chung finished the game with six tackles. With an entire offseason to recover, the veteran safety will likely be recovered in time for training camp, barring a setback.

Chung finished the 2017 regular season with 84 tackles and a pick in 16 games.

EDGE Analysis

Drafted by the Patriots in the second round of the 2009 NFL Draft, Chung left the team after the 2012 season via free agency, signing a three-year, $10 million with the Eagles. After being cut by Philadelphia following just one season, Chung resurfaced with the Patriots and he's been a mainstay of the team's defense since then.

Chung made a season-high 10 tackles (nine solo) against the Dolphins on Sunday.

EDGE Analysis

Chung posted a season-high nine tackles in Week 11, then topped it in Week 12. The veteran safety is beginning to thrive after a slow start, as he has played every defensive snap for the second consecutive week.

Chung (ankle) will play in Sunday's game against Miami.

EDGE Analysis

Chung was limited in practice Thursday and Friday but his injury doesn't appear severe enough to sideline him. Though it isn't clear if he's 100 percent, he'll be expected to start and see his typical role on the defense.

Chung (ankle) is listed as questionable for Sunday's matchup against the Dolphins.

EDGE Analysis

Chung presumably injured his ankle last week against the Raiders. After watching Wednesday's practice from the sidelines, he practiced in limited fashion Thursday an Friday. An official ruling on his status is unlikely to be made until closer to game-time Sunday. Jordan Richards would be the likely candidate to fill in at strong safety should Chung ultimately sit out.

EDGE Analysis

Chung's previous high in tackles was eight (seven solo) in a Week 2 victory over the Saints. The veteran safety managed to do all his work across 55 snaps (87.0 percent). He will look to carry that momentum into Sunday's game against the Dolphins.
