Chargers general manager Joe Hortiz said Thursday that Johnston isn't on the trade block, Kris Rhim of ESPN.com reports.
"There's a lot of rumors out there on Twitter," Hortiz said. "And I can tell you this, I have made zero calls about Quentin, and I've had zero calls regarding Quentin." Johnston is heading into the fourth year of his rookie contract, and the Chargers have until May 1 to decide whether to pick up the 2023 first-round pick's $18.1 million fifth-year option for 2027. The 6-foot-2 wide receiver has recorded eight touchdown catches in each of the last two regular seasons, but Johnston has struggled with drops throughout his NFL career.
