Tre’ Harris answered the call in perhaps the biggest play of his rookie season so far.

With the Chargers trailing Sunday in Kansas City at the end of the first half, the second-round pick won his 1-on-1 matchup on the outside and hauled in a perfectly placed ball down the sideline from Justin Herbert for 37 yards.

It was Harris’ longest reception of his debut campaign and would lead to a crucial Bolts touchdown to end the half.

“That’s a catch, the whole receiver room, practices every day,” Harris said this week. “That’s all I really want, just muscle memory. Being able to flip the momentum, especially when we needed a change in that moment.

“We needed a big play and were going into a big drive, I was glad to be able to have that moment and flip the script a little bit and get us in a good position,” Harris added.

Herbert said: “We know how talented and athletic Tre’ is and I think he’s going to make so many big plays and has already made a ton this year. For him to go up there and catch that pass, it was huge for us to set up that touchdown and kind of get us back into the game.”

As Harris enters the final stretch of his rookie season, his progression and growth are clear.

Harris has held a steady role in the offense throughout the season but come on strong as of late by playing in 50 percent or more of the offensive snaps in the last four games.

And with Quentin Johnston out with an injury in the Chiefs game, Harris was called upon to fill a significant role and leading all wide receivers with 56 snaps.

Harris knew heading into the game he would be more involved, but whether he heads into a game being a focal point or not, he said it doesn’t change much of his approach.

“Nothing really changed to be honest with you,” Harris said. “For me, going into the game I’m in the mode where I’m ready for whatever. Whatever happens, whatever a guy needs, no matter the situation.

“Unfortunately, Q was banged up with an injury so my mindset immediately just set to the position itself and make sure I key in on all the small details and go in and execute,” Harris added.
