The 49ers have stormed out to a 4-1 start despite a slew of injuries to important contributors. With the Nov. 4 trade deadline looming as a key improvement avenue, Cam Inman of the Mercury News expects general manager John Lynch to deal for outside help in the next few weeks. More specifically, it is likely that the 49ers at least want to acquire an edge rusher, according to Vic Tafur of The Athletic.
The pass rush became an obvious area of concern for the 49ers when defensive end Nick Bosa tore the ACL in his left knee in Week 3. That injury ended a season that began in promising fashion for the former Defensive Player of the Year. Bosa totaled 17 tackles, two sacks, and two forced fumbles in the early going this year.
Despite their strong start, the 49ers have had a difficult time getting to enemy quarterbacks since losing Bosa. The rest of their defense has accounted for just four sacks, and the team’s total (six) ranks 30th in the league.
It doesn’t help matters that the 49ers’ Bosa-less defensive line is now dealing with injuries to Yetur Gross-Matos (hamstring), Kalia Davis (hand), and Alfred Collins (knee). While Collins could play this week against the Buccaneers in a battle of 4-1 NFC teams, Gross-Matos and Davis are expected to miss time.
Unfortunately for San Francisco, nobody from the Gross-Matos/Davis/Collins group has registered a sack this year. The same is true of Mykel Williams, the 11th overall pick in this year’s draft. Williams has played 68.6% of defensive snaps as a rookie, but his production hasn’t been great through his first five games. Pro Football Focus ranks his performance 128th among 169 qualifying EDGE players.
Other than Bosa, Bryce Huff is the only D-lineman on the team who has taken down an opposing QB in 2025. Huff, acquired from the Eagles in June, has notched three sacks and a forced fumble over his first five games with San Francisco. He also ranks 19th among EDGE players in pass rush win rate. It’s worth noting that Huff posted a career-high 10 sacks with the Jets in 2023. Niners defensive coordinator Robert Saleh was the Jets’ head coach then, and it seems he’s once again getting the most out of Huff after a 2.5-sack showing with the Eagles in 2024.
If pass-rushing complements to Huff don’t emerge from within over the next month, it wouldn’t be a surprise to see the aggressive Lynch swing one or more deals. Lynch has a long history of deadline activity — at D-end alone, the 49ers have traded for Charles Omenihu, Randy Gregory and Chase Young in-season since 2021 — and is armed with roughly $24MM in cap space, which will make it easier to maneuver on the market.
PFR’s Ely Allen identified the Dolphins‘ Jaelen Phillips as a trade candidate and a potential fit for the 49ers earlier this week. The Saints, who are expected to sell at the deadline, could move eight-time Pro Bowler Cameron Jordan. The Titans also roster ex-49er Arden Key, who left San Francisco via free agency in 2023, and sit 1-4. It’s a long shot, but Bengals star and soon-to-be free agent Trey Hendrickson could be worth monitoring if they fall out of contention over the next few weeks. For now, having traded for quarterback Joe Flacco on Tuesday, the Bengals are still trying to stay alive for a potential Joe Burrow return from IR later in the season.
