SANTA CLARA, Calif. (AP) — Radio announcer Kevin Harlan used a fan who ran onto the field to spice up his call of Monday night's game between the Los Angeles Rams and San Francisco 49ers, offering spirited play-by-play commentary as security chased down the fan.

The Westwood One announcer enthusiastically jumped into action when the fan ran onto the field with the 49ers holding a 21-0 lead in the fourth quarter, calling out the fan's movements like he would a long touchdown run before finishing with "they tackle him at the 40-yard line" when security finally caught up.

Referring to the 49ers blowout, Harlan called the moment "the most exciting thing to happen tonight."

The announcer may be right. His call of the action has become a trending topic on Twitter.

Hear Harlan's call in the video below.
