WATCH: Larry Fitzgerald throws 1st touchdown pass of his career

If Sunday was indeed Larry Fitzgerald's final game in Arizona, he picked one heck of a way to go out.

In the second quarter of the Arizona Cardinals' game vs. the Los Angeles Rams on Sunday, Fitzgerald threw a touchdown pass -- a perfect 32-yard toss to running back David Johnson. The play cut the Rams' lead to 14-9.

In his 15-year career, Fitzgerald has caught 115 career touchdown passes. The pass to Johnson was the first TD he's ever thrown.

"It’s been in (the playbook) for several weeks now, and we’ve been working on it for a while," Cardinals coach Steve Wilks said after the game. "(Offensive coordinator Byron Leftwich) called it at the right time. It was a great play."

Fitzgerald, who also caught six passes for 63 yards Sunday, joked about the play after the game, noting it was his first touchdown pass since high school.

"I guess it’s like a layup in basketball. You can’t miss it. It came out a little wobbly; it looked like (former Cardinals quarterback) Kurt Warner’s ball. But like Kurt Warner’s (throws), it was effective," he said.

Sadly, Fitz's throw was the Cardinals' only touchdown of the game, as the Cardinals fell to the Rams 31-9 on Sunday to move closer to getting the No. 1 pick in next year's draft.

Sunday's game was the last at home for the Cardinals this season; they'll wrap up the 2018 season at the Seattle Seahawks next weekend.

Fitzgerald hasn't given any hints as to his future plans in the NFL, as retirement rumors are swirling around him for the third straight year. On Sunday, Fitzgerald texted support for coach Steve Wilks, despite a report that Wilks will be let go at the end of the season.
