The San Francisco 49ers are no strangers to the injury grindstone, but even for a franchise accustomed to punching above its weight through sheer grit and scheme, the 2025 season is testing their limits early. Sitting pretty at 2-0 after gritty wins over a pair of NFC South foes, the Niners are suddenly staring down a depleted roster that could derail their Super Bowl repeat dreams before the calendar flips to October. The latest casualty? Their already patchwork offensive line, now so thin it’s prompting emergency tryouts just days before a pivotal divisional clash with the undefeated Arizona Cardinals.
It’s a cruel irony: Head coach Kyle Shanahan’s offense, long a model of efficiency and explosiveness, has been reduced to a makeshift operation. Quarterback Brock Purdy sat out Week 2’s thriller against the New Orleans Saints with an undisclosed issue, handing the reins to veteran backup Mac Jones. Tight end George Kittle, the heart and soul of San Francisco’s pass-catching corps, was sidelined with a hamstring strain severe enough to land him on injured reserve—potentially for the lion’s share of the season. And that’s before you even get to the trenches, where the Niners’ front five has been battered like a piñata at a kid’s birthday party.
Star left tackle Trent Williams, the 37-year-old future Hall of Famer, gutted out a full game in Week 2 despite nursing a lingering knee injury that had him listed as questionable all week. He played every snap, stonewalling pass rushers with the vintage tenacity that’s defined his career, but whispers from the locker room suggest he’ll be managed carefully moving forward. If Williams aggravates it? Disaster looms.
The real gut punches, though, came from the interior. Starting left guard Ben Bartch, a key free-agent addition last offseason, twisted his ankle in practice last week and is expected to miss multiple games—perhaps even the entire month. Then, compounding the chaos, backup left tackle Spencer Burford went down with a knee injury of his own during preparations for Week 2. Shanahan confirmed Monday that Burford will be sidelined for at least a couple of weeks, leaving the Niners perilously short on swing depth at a position that’s already operating at half-staff.
“Spencer’s tough as nails, but this one’s gonna sting,” Shanahan said post-practice, his voice carrying the weight of a coach who’s seen too many seasons hijacked by the training room. “We’re not making excuses, but we can’t ignore the math here. We need bodies—good ones—who can step in and protect Mac [Jones] long enough for him to make plays downfield.”
Enter the tryout carousel, a time-honored NFL ritual that reeks of desperation but often yields hidden gems. On Tuesday, the 49ers’ front office—led by general manager John Lynch—rolled out the red carpet (or at least the Santa Clara practice fields) for five battle-tested offensive linemen, all vying for a shot at the active roster or practice squad. It’s a clear signal: San Francisco isn’t waiting for the waiver wire to bail them out. They’re hunting reinforcements now, with roster moves potentially announced as early as Wednesday.
The invitees form an intriguing mix of grizzled vets, journeymen with starting pedigrees, and intriguing young upside plays:
- Brandon Parker (OT, 29): A third-round pick by the Raiders in 2018 out of North Carolina A&T, Parker has logged 59 games and 33 starts, all in silver and black. He’s got the size (6-foot-8, 325 pounds) and experience to slide in at tackle, either as Williams’ insurance or in a pinch at guard. Parker spent time on the 49ers’ practice squad earlier this year before latching on with the Falcons. His familiarity with Shanahan’s zone-blocking scheme? Priceless.
- Le’Raven Clark (OT/G, 32): Another third-rounder, this time by the Colts in 2016 from Texas Tech, Clark brings a decade of pro football under his belt. He’s appeared in 64 games with 18 starts across stints in Indianapolis, Tennessee, and Pittsburgh, excelling as a versatile interior swingman. At 6-foot-5 and 315 pounds, he’s the kind of plug-and-play option who could stabilize the left side overnight.
- Christopher Hubbard (OT/G, 34): Undrafted out of Alabama in 2013, Hubbard has carved out a journeyman’s career with 102 games and a whopping 61 starts. He’s bounced from Pittsburgh to Cleveland, Tennessee, and New York, and even suited up for the 49ers’ practice squad in 2024. A mauler in the run game with sneaky athleticism in pass pro, Hubbard’s the elder statesman of the group—experienced enough to mentor, tough enough to start Sunday if called upon.
- Zachary Thomas (OL, 27): A sixth-round steal by the Bears in 2022 from South Dakota State, Thomas has bounced around the league with stops in Chicago, Los Angeles, New England, and Houston. In 17 career games, he’s shown flashes as a developmental tackle with guard flexibility, standing at 6-foot-4 and 308 pounds. He’s raw but hungry—a classic “high-upside flier” for a depth chart in flux.
- Matt Waletzko (OT, 25): The youngest of the bunch, Waletzko was a fifth-round pick by the Cowboys in 2022 from North Dakota. He appeared in 11 games over his first three seasons in Dallas before getting waived in preseason this year. At 6-foot-7 and 312 pounds, he’s got the length and leverage to develop into a franchise tackle, but his limited snaps (mostly special teams) make him more of a long-term project than an immediate fix.
No deals have been inked yet, but the tea leaves point toward at least one signing—likely Parker or Hubbard, given their Niners ties and proven tape. As NBC Sports Bay Area’s Matt Maiocco reported on X: “The 49ers today held tryouts with five offensive tackles: Brandon Parker, Le’Raven Clark, Christopher Hubbard, Zachary Thomas and Matt Waletzko. Backup LT Spencer Burford has a knee injury, coach Kyle Shanahan said on Monday.”
This isn’t just about plugging holes; it’s about survival. With Jones under center—a signal-caller who’s thrived in protected pockets but wilted under blitzes—the offensive line’s job borders on mission-critical. San Francisco’s Week 2 win over the Saints was a 24-20 nail-biter fueled by Deebo Samuel’s heroics and a bend-but-don’t-break defense, but it masked the underlying fragility. Jones completed 18 of 25 for 192 yards and a touchdown, but he absorbed three sacks and hurried throws on 22 percent of his dropbacks. In a division where the Cardinals’ pass rush—led by a resurgent Haason Reddick—ranks top-five in pressures through two weeks, another afternoon of musical chairs up front could spell doom.
Yet, for all the gloom, there’s a flicker of 49ers defiance. They’ve navigated injury epidemics before—remember the 2021 run to the NFC Championship with half their stars in street clothes?—and emerged tougher for it. Shanahan’s staff has a knack for turning lemons into Lombardi-worthy lemonade, and with Christian McCaffrey churning yards on the ground and Brandon Aiyuk stretching defenses vertically, there’s enough firepower to keep defenses honest.
Week 3 at Levi’s Stadium (4:25 p.m. ET, FOX) against Arizona won’t be a cakewalk. The Cardinals, riding high on Kyler Murray’s MVP-caliber start and James Conner’s bell-cow efficiency, are 2-0 and hungry to flip the NFC West script. A win here catapults San Francisco into sole possession of first place, a statement that the injury bug won’t break them. A loss? It invites questions about sustainability, the kind that echo through the Bay Area come December.
For now, the focus is tryouts and tape. Will Parker reclaim a starting gig? Can Hubbard summon one more Steelers-worthy season? Or does a dark horse like Waletzko steal the show? In the NFL’s unforgiving ecosystem, crises forge champions—or expose frauds. The 49ers, battered but unbowed, are betting on the former. Kickoff can’t come soon enough.
