The San Francisco 49ers secured a decisive 32-19 victory over the New York Jets in their season opener, despite the unexpected absence of star running back Christian McCaffrey due to a calf strain. Backup Jordan Mason stepped up impressively, rushing for 147 yards on 28 carries in his first career start, showcasing his growth and maturity since joining the NFL as an undrafted free agent. The Jets struggled throughout the game, with coach Robert Saleh admitting they were dominated up front, highlighting the 49ers' physicality and effective running game. McCaffrey's injury raised concerns after he was deemed inactive just before the game, despite earlier assurances about his readiness to play. The game also featured an odd moment when Jets cornerback Sauce Gardner was sidelined briefly for breath, and injuries plagued the Jets with Michael Carter II exiting late in the game. Overall, Mason's performance and the 49ers' strong offensive display indicated their potential moving forward in the season.
