SANTA CLARA, Calif. — In a bombshell development that’s left 49ers Nation reeling, former San Francisco 49ers quarterback Mac Jones announced his abrupt retirement from the NFL on Monday morning, mere hours after being waived by the team following their heartbreaking 26-15 loss to the Houston Texans on October 26, 2025. The 27-year-old, who stepped in as the starter amid Brock Purdy’s shoulder injury, cited mounting pressure and a pivotal interception that “sealed our fate” as the breaking point. In a poignant X post that’s already amassed over 150K likes, Jones wrote: “Football gave me everything, but today I give it back. Sorry I couldn’t deliver for the Niners. Grateful for the ride. #Retiring.” The move caps a turbulent 2025 season for Jones, who signed a two-year, $7 million deal with San Francisco in March as a backup but found himself thrust into the spotlight—only to falter when it mattered most.

Jones’ final game was a microcosm of his Niners tenure: flashes of promise drowned in critical errors. Filling in for the sidelined Purdy (turf toe and shoulder woes), Jones went 19-of-32 for 193 yards, with two touchdowns (one to George Kittle, one to Jake Tonges) but a back-breaking interception to Texans CB Kamari Lassiter with 1:56 left. Targeting WR Jauan Jennings at the Houston 1-yard line, the pick halted a potential game-tying drive, allowing C.J. Stroud’s squad to kneel out the clock. “That throw haunts me,” Jones confessed in his postgame presser, per ESPN transcripts. “I misread the coverage, held the ball too long under pressure. We had momentum, and I cost us the game.” His 84.5 passer rating and two sacks (-18 yards) underscored a 21% pressure-to-sack rate (via Pro Football Focus), a glaring weakness compared to Purdy’s elite 6.1%. The offense sputtered with just 237 total yards and 14 first downs, as Christian McCaffrey managed only 62 rushing yards against Houston’s vaunted D.
The waiver wire buzzed by noon ET, with the 49ers citing “roster management” amid a bye week reset. Sources tell The Athletic it’s tied to Jones’ postgame candor: “I just didn’t feel like we had a chance out there,” he admitted, praising the Texans’ defense as “the best in the NFL” after facing them thrice in a year. HC Kyle Shanahan, in a measured response, said: “Mac’s a pro who owned his mistakes. Tough call, but we need to rally around Brock’s return.” Purdy, expected back for Week 9 vs. the Giants, tweeted support: “Brother, you fought hard. Door’s always open.”
Jones’ arc with the 49ers was a redemption saga gone awry. Traded from New England in 2024 after a Pro Bowl rookie year (2021) devolved into benchings, he inked with SF as insurance for Purdy. Early 2025 wins (3-0 stretch, including 342 yards vs. Rams) sparked “QB1” chatter, but recent flops—like this Texans clunker—exposed his pocket-bound style and mental lapses. Fan frustration boiled over: #BenchJones trended with 70K posts postgame, memes splicing his INT with Trey Lance’s infamous 2021 draft slide (SF passed on Jones at No. 3). “He had the tools but crumbled in crunch time,” Yardbarker analyst Clark Dalton wrote. “Niners dodged a bullet.”
Now 4-4 and tied atop the NFC West, the 49ers pivot to veteran Sam Darnold (claimed off waivers) as Purdy’s bridge, per NFL Network’s Ian Rapoport. Shanahan eyes trade deadline deals (Nov. 4) for edge help sans Nick Bosa. For Jones, the Alabama legend (NCAA records in completion % and passer rating) exits with 6,500 career yards, 42 TDs, and a what-if legacy. “I gave my all until I couldn’t,” he added on X. “Time for new chapters.”
Niners faithful are gutted yet reflective—Jones’ honesty humanized him amid the chaos of injuries and ref controversies (shoutout to Wilson and Montana’s rants). As Levi’s Stadium quiets for bye week, one truth lingers: In the NFL’s unforgiving arena, even saviors can become scapegoats overnight.
