During the second quarter of the Rams’ 24-9 loss to San Francisco, security personnel chased man who ran onto the field with a smoke bomb toward the Rams sideline. That’s where the 6-foot, 241-pound Wagner took him down. Rams linebacker Takkarist McKinley was also closing in for a tackle. The unnamed man was tackled before being taken into the custody of law enforcement. “I just saw somebody running on the field — and he wasn’t supposed to be on the field,” Wagner said. “I saw security was having a little problem, so I helped ‘em out.” The alleged animal rights activist has filed a police report at the Santa Clara Police Dept. against Wagner. An organization called Direct Action Everywhere is taking credit for the wild antics at the stadium and a rep for the group claims the activist was the victim of a “blatant assault”. Wagner responded to the police filing on Wednesday, telling reporters, “It’s behind me. Can’t really focus on it. I’m more concerned about the security guard that was hurt trying to chase him and the people that was … we don’t know what that is and you just gotta do what you gotta do.” Wagner, 32, is in his 11th NFL season, his first with the Rams after 10 with the Seattle Seahawks. He said he was “just keeping it safe” when he decided to act.
