So many football fans have been reacting to the tragic news on Facebook, Twitter and other social media. Their hearts go out to Adrian Peterson and to the Sioux Falls mother of the two-year-old boy. But it's not just Vikings fans who are touched and saddened by this news.
He's the game's biggest star, but Peterson received the darkest news any parent could receive.
His two-year-old son was beaten allegedly by the mother's boyfriend, Joseph Patterson.
For many the news is sad, no matter who it happened to.
"It's just terrible to hear that that would happen to any kid, let alone a professional athlete who is probably the best professional athlete in his sport," Chad Barman said.
"I was surprised that his son was in Sioux Falls and to hear what happened to such a little child is pretty shocking. I have two little nieces and I couldn't imagine if something like that happened to my little nieces," Jeremy Botzet said.
Peterson was seen in Sioux Falls on Thursday at a local bar and restaurant. It caught many off guard, but now they understand why the reigning MVP came to Sioux Falls, saying he did the right thing.
"He's got a lot of commitments to come all the way from Minnesota. He has to play again on Sunday. He's got to leave the team for practice. It's a great test to the person he is to be able to come back and leave his team, leaving his job to come back to be with his son. I think that's something that's important in life," Nate Winter said.
And when there's tragic news like this, people often times look for the good.
"Obviously because it is Adrian Peterson, so more people are hearing about it, I just hope it brings about more awareness for child abuse in general because it's a horrible thing," Katie Schlemmer said.
Just after 5 p.m. on Friday, Peterson posted on Facebook to thank fans for their support.
