It was his first game back after missing last week’s game — and it was perhaps the most highlight-filled game of his career to date.
Johnston got the game started on the opening offensive drive for the Chargers with perhaps the best catch of his career.
Finding himself 1-on-1, Johnston got a step on the cornerback and made his way to the back of the end zone, where Justin Herbert dropped in a ball he snagged with one hand.
“Tremendous,” Harbaugh said. “One of the best catches of his career.”
Herbert added: “Those passes where you believe in him. It’s, ‘You know what, I’m betting on Q.’ Then he goes and makes some big plays.”
The stellar one-handed touchdown grab was the eighth of the season for Johnston as he became the first Charger since Antonio Gates to catch at least eight touchdowns in back-to-back seasons.
Johnston wasn’t done, however, as he came back early in the second half with another highlight.
On the second play of the third quarter, Herbert stepped up in the pocket and uncorked a back shoulder ball deep down the sideline to give Johnston a chance in another 1-on-1 situation.
Not only did the third-year receiver leap and make the grab over a defender, he got his feet inbounds for a massive chunk gain of 50 yards.
He’s shown his big play ability before and did just that on Sunday in a big way.
“Definitely shows my growth and my hard work and stuff like that,” Johnston said.
He later added: “To get to this moment, proud of myself.”
