The Los Angeles Rams defense may have struggled to 

tackle San Francisco 49ers wide receiver Deebo Samuel for 

a 57-yard touchdown Monday night in the second quarter, 

but linebackers Bobby Wagner and Takka List McKinley scored on 

a half-hit that night Just before halftime, a fan carried what appeared to be 

a device emitting pink smoke across the field of Levi's Stadium.

This person evaded security and walked to the Rams' touchline.

The collision left a clear trail near his line forty yards of the field.

Early in Monday night's game, a fan rushed onto the pitch with 

 a device emitting pink smoke, but was stopped by security.
