TEMPE, Ariz. (AP) -- Arizona Cardinals defensive tackle Darnell Dockett spews out so many Twitter messages, it's hard to keep up.

One this week, though, in advance of Arizona's game at Atlanta on Sunday, was special.

It read: "I think I'm going to dedicate sunday game to my MOM she was killed when I was 13 I might cry B4 the game."

Dockett returned to his Decatur, Ga., home that day to find his mother shot to death in the head, a crime that hasn't been solved.

He went to live with his father, who died a few months later of pancreatic cancer. An uncle is credited with saving him, helping him avoid a life of drugs and crime on the street.

Dockett said Wednesday that he will go back to his old neighborhood this weekend and round up 20 or so youngsters and "take them shopping."
