The San Francisco 49ers officially signed edge rusher Jah Joyner to a one-year deal today, making a quick move that says a lot about their defensive line situation. This transaction was directly tied to another big roster shift: Victor Dimukeje, who just signed with the team on August 17, is already headed to the Injured Reserve List. Talk about a whirlwind; it means Joyner is brought in as an immediate replacement for Dimukeje, likely eyeing some snaps in tonight’s preseason finale.
Who Is Jah Joyner and Why Do The Niners Need Him?
Joyner’s path to the 49ers has been a bit of a journey. After going undrafted in 2025, he previously played for the Las Vegas Raiders, where he got 52 snaps in the preseason but never hit the field during the regular season. The guy’s a beast at 6’5″, 265 pounds, and lines up exclusively on the edge. He spent last season playing 10 games in the UFL and even had a tryout with the Steelers back in June 2026, though nothing came of it until now. The fact the Niners are scrambling to work out a pass rusher the day before their final preseason game just screams “we need bodies.” They don’t want to risk their Week 1 starters in what’s essentially a meaningless game for those top-tier players.
The Edge Rush Is A Problem Right Now
This signing highlights some real depth concerns for the 49ers’ edge rush. Romello Height has been nursing an ankle injury, and while the team wants him at 100% for Week 1, they would have loved to see their rookie get more live game reps. That injury alone is a huge reason they’d host a tryout for another edge rusher. For tonight’s game, things look even more dicey with Nick Bosa, Mykel Williams, and Keion White all projected to be out. That leaves Quinton Bell, Ogbo Okoronkwo, and Villiami Fehoko Jr. as the primary edge rushers. Sam Okuayinonu, who’s pegged as Mykel’s replacement for early-down run defense, is on track to start, but he’s too important to risk with an injury and probably won’t be out there tonight. This whole situation for the Niners shows they’re really trying to patch things up on the fly before the regular season kicks off.
Tonight’s game is their last chance to get some reps for these new guys and figure out what they have before Week 1. They’ll be looking to see if Joyner can actually contribute quickly or if this is just a bandage on a bigger wound for their defensive line.
