The San Francisco 49ers’ preseason clash with the Los Angeles Chargers on August 20, 2026, may have been billed as just another tune-up, but for running back Sincere McCormick, it was anything but ordinary. The 25-year-old back, who entered training camp as a long shot to make the 49ers’ 53-man roster, delivered a performance that has the Bay Area buzzing and coaches rethinking their depth chart. With a dazzling 37-yard burst and a gritty seven-yard touchdown run, McCormick seized his moment under the bright lights and made a compelling case for a permanent place in San Francisco’s crowded backfield.
Let’s set the stage: the 49ers, coming off a season where running back depth was both a blessing and a curse, have watched their ranks thin due to injuries. Most notably, Patrick Taylor Jr. was recently placed on injured reserve, opening up a coveted spot in the running back rotation. Enter McCormick, who had already bounced around five NFL teams without ever truly finding a home. With the odds stacked against him, the former undrafted free agent knew this preseason could be his last real shot at sticking in the league.
And did he ever make it count! Early in the game against the Chargers, McCormick took a handoff, read his blocks, and exploded through a gap for a 37-yard gain that electrified both the crowd and his teammates. The run showcased his vision, patience, and breakaway speed—qualities every NFL team covets in a ball carrier. Later, he capped off the drive with a determined seven-yard touchdown rush, barreling through contact and falling forward into the end zone despite being hit by multiple defenders at the two-yard line. As one fan marveled on social media, “Three Chargers hit Sincere McCormick at the 2+ yard line and he still fell forward into the end zone.”
That score—featured prominently in NFL game highlights—was more than just another stat on the sheet. It was a statement. McCormick’s ability to finish runs, even when the defense had the angle, turned heads across the league. NFL reporter Dontay Atkinson summed up the general sentiment, writing, “Sincere McCormick is taking full advantage of the opening he’s got now with Patrick Taylor going to IR. He’s got a legit shot to make the 53.”
But it wasn’t just about one big play or a single touchdown. Throughout training camp and the preseason, McCormick has been a model of consistency and availability—two traits that coaches value, especially in a position group battered by injuries. According to SF Standard’s David Lombardi, the fifth running back spot is now wide open, and McCormick has positioned himself as a leading candidate. “Longshot to make the roster but has been available and heavily involved every day when injuries have decimated the RB room,” noted NFL reporter Nick Wagoner, who also dubbed McCormick the “unsung hero” of the 49ers’ preseason and training camp.
For McCormick, the journey to this pivotal moment has been anything but straightforward. After stints with five different NFL franchises, the young back has learned to embrace uncertainty and keep grinding. His resilience and relentless work ethic have not gone unnoticed inside the 49ers’ facility. Coaches have praised his effort, and his teammates have rallied around his underdog story. “I love how Sincere McCormick set up that big run. Froze the LB crazy,” one fan observed, highlighting the subtle skills that set McCormick apart from other hopefuls.
Still, the reality of the NFL is harsh. Even with a standout performance, roster spots are scarce, and the 49ers’ backfield remains one of the deepest in the league. Analysts like Vic Tafur have pointed out that, despite McCormick’s impressive showing, he “likely won’t make the 49ers roster,” though Tafur was quick to add there’s no question McCormick belongs as an NFL running back. That’s the paradox facing McCormick: he’s proven he can play at this level, but will it be enough to secure a spot in San Francisco, or will another team swoop in if the 49ers let him go?
The uncertainty hasn’t dampened the excitement among fans, who have taken to social media and message boards to voice their support. “I kinda like Sincere McCormick man, he’s really not bad lol,” wrote another fan, capturing the growing groundswell of grassroots enthusiasm. For a player who began the summer as a roster afterthought, McCormick has become the talk of training camp.
What makes McCormick’s story so compelling is how he’s capitalized on every opportunity. When injuries hit the running back room, he didn’t just fill in—he excelled. His 37-yard run wasn’t a fluke; it was the product of smart footwork, patience behind his blockers, and a burst that left defenders grasping at air. His touchdown run? Pure determination and power, refusing to be denied when it mattered most.
Coaches often preach the importance of “next man up,” but few players embody that mantra quite like McCormick has this preseason. His availability, drive, and consistent effort have made him a favorite among position coaches and a source of inspiration in the locker room. As the preseason winds down and final roster decisions loom, McCormick’s name is now firmly in the mix—something that seemed improbable just a few weeks ago.
Of course, the competition remains fierce. The 49ers’ backfield features established stars and promising young talent, making the fight for the final roster spot as intense as any in the league. But if McCormick’s recent play is any indication, he’s not backing down. He’s running with purpose, playing with confidence, and doing everything in his power to make the decision as difficult as possible for the coaching staff.
As the dust settles on the Chargers game and the 49ers prepare for their next preseason test, all eyes will be on McCormick. Will his breakout performance be enough to secure a spot on the 53-man roster? Or will he once again find himself searching for a home in the cutthroat world of the NFL? For now, one thing is certain: Sincere McCormick has made people take notice, and his story is far from over.
The preseason drama continues, and with every carry, McCormick is writing a new chapter in his NFL journey. Whether he ultimately makes the 49ers’ roster or not, his determination and resilience have already left a mark on this team—and given fans plenty to cheer about as the regular season approaches.
