MINNEAPOLIS (WCCO) — Minnesota Vikings running back Adrian Peterson is playing Sunday at the Metrodome — just days after his 2-year-old son died, an apparent victim of a brutal beating at the hands of another man.

Before Peterson hit the field, fans were showing their support for AP during this difficult time.

“The first time I heard it, I just couldn’t believe it. It’s just sad, you know, who would do something like that you know what I mean?,” one fan said, going into the game.

Another called it a “wake-up” call to raise awareness about the problem of child abuse.
