Jaguars Upset 49ers; Saleh-Coen Sideline Clash

Jacksonville upset the previously undefeated San Francisco 49ers 26–21 in Week 4, featuring a 48-yard Travis Etienne touchdown, an 87-yard punt return and zero turnovers. The game followed pregame remarks from 49ers defensive coordinator Robert Saleh that Jaguars coach Liam Coen and his staff run a legally advanced “signal‑stealing” system using formations and pre‑snap tells. After the game a heated sideline exchange between Coen and Saleh required players and staff to separate them; Coen publicly downplayed the incident and said he would keep it “between us.” 49ers coach Kyle Shanahan and others suggested Saleh intended the comments as a compliment to Jacksonville’s staff, while at least one veteran coach criticized Coen for creating an avoidable news item. Jacksonville hopes to carry the momentum into Monday’s matchup against the Kansas City Chiefs.
