The fan who ran onto the field during Monday Night Football between the Los Angeles Rams and San Francisco 49ers has filed a police report against Bobby Wagner.

Shortly before halftime at Levi's Stadium, a fan ran across the field with what appeared to be a device letting out pink smoke. Rams linebacker Takkarist McKinley came toward the person then Wagner stepped in and laid him out with a big hit.

Santa Clara Police Department Lt. Cuong Phan confirmed on Wednesday that the police report was filed Tuesday afternoon. 

According to TMZ Sports, the individual is an activist for the Berkeley, California-based animal rights group Direct Action Everywhere and was trying to "raise awareness for a trial involving the alleged theft of pigs from a factory farm."
