Rams linebacker Bobby Wagner tackled a fan who ran onto the field, and Peyton Manning loved it

• A fan ran onto the field during "Monday Night Football," briefly interrupting the Rams-49ers game.
• The Rams linebacker Bobby Wagner ended the fan's fun with a big hit from the sidelines.

A fan who stormed the field during Monday night's game between the Los Angeles Rams and the San Francisco 49ers messed around and found out.

The fan took to the field carrying a pink smoke flare, briefly interrupting play. While the fan evaded security as he made his way to the Rams sideline, he was met with some resistance.

The defensive end Takk McKinley stepped out and briefly gave chase before the linebacker Bobby Wagner stepped up and put a shoulder into the fan, swiftly ending his sprinting session.

Fans in the stadium captured video of the incident.

On ESPN2's "ManningCast," Peyton Manning cheered on Wagner's effort.

"Yes! Yes!" Manning said as he watched a replay of the hit. "That's what we're talking about. Wagner, a veteran. Get him down. Now get out, and let these guys take over."

Let this be yet another reminder to anyone even momentarily considering doing something extremely stupid: It is never a good idea to run onto an NFL field unless you are a bona fide NFL player.
