Recent Fantasy Football Defense News
Jonathan Greenard, Philadelphia Eagles
The Philadelphia Eagles traded for edge rusher Jonathan Greenard (pectoral) during the 2026 NFL Draft, and they promptly extended him with a four-year, $100 million deal, but he began training camp on the physically unable to perform list after suffering a pectoral strain while lifting weights, and his Week 1 availability is now in doubt. When asked on Wednesday if there was any concern Greenard could miss the start of the season, Eagles defensive coordinator Vic Fangio kept his answer short, simply saying, "Yeah."
A Pro Bowler in 2024, Greenard disappointed in his final season with the Vikings, totaling only three sacks while missing five games with a shoulder injury, but he was viewed as an important piece in replacing Jaelan Phillips, whom the team could not retain after trading for him in 2025. Should Greenard miss time to begin the year, Philadelphia will go into 2026 with a top pass-rushing tandem of Nolan Smith and Jalyx Hunt.
Nick Bosa, San Francisco 49ers
San Francisco 49ers head coach Kyle Shanahan said that edge rusher Nick Bosa (knee tendinitis) is doing better, with his symptoms improving. Bosa missed the past week due to knee tendinitis related to his ACL tear, which he suffered early last season. Shanahan said on Tuesday, "He's making a lot of progress. He's got a lot less irritation, soreness, tendinitis, whatever you want to call it, than he had last week.
He's going in the right direction, and I see him similar to Christian [McCaffrey]." The 49ers reportedly struggled during their joint practice against the Los Angeles Chargers, getting beat consistently on edge sets and play-action passes. If Bosa can't return before they travel to Melbourne to face the Los Angeles Rams, they'll face a difficult challenge because of the Rams' outside zone runs and their effective use of play-action passes.
Za'Darius Smith, Atlanta Falcons
The Atlanta Falcons signed veteran pass rusher Za'Darius Smith on Tuesday, bringing the three-time Pro Bowler out of retirement less than a year after he stepped away from the NFL. Smith retired on Oct. 13, 2025, after playing five games for Philadelphia, where he recorded 1.5 sacks.
He was much more productive the year before, finishing 2024 with nine sacks while splitting time between Cleveland and Detroit. Atlanta has an immediate need on the edge. Jalon Walker is out for the season with a torn ACL, while James Pearce Jr. will miss the first eight games because of a league suspension. Smith also has some familiarity with head coach Kevin Stefanski from their time together in Cleveland. He turns 34 in September and has not played since last October, so his early workload is still something to watch. Even so, Smith brings 70.5 career sacks to a Falcons front that suddenly needed another proven option.
Von Miller, Dallas Cowboys
The Dallas Cowboys are expected to sign free-agent linebacker Von Miller, according to Adam Schefter of ESPN.com. Presumably, it'll be a one-year deal for the veteran defensive standout. Miller is an eight-time Pro Bowler, but he hasn't earned the honor since 2019.
Nevertheless, he has remained productive deep into his career. Last year with the Commanders, he played in 17 games, amassing 26 tackles, nine sacks, 15 quarterback hits, and six tackles for loss. Now 36 years old, the Texas A&M product and Texas native heads to Dallas for a homecoming of sorts. He should offer depth in a linebacker room that is headlined by Rashan Gary, Dee Winters, DeMarvion Overshown, and Donovan Ezeiruaku.
