Scott Lyon told SN-TV in Wichita, Kan., that Williams happened to be in town Saturday night and spent about 30 to 45 minutes "chainsawing" and "cutting branches" before leaving to catch a flight to St. Louis.
"He's a really nice guy," Lyon said. "He went out and helped in a community he doesn't live in. He just wanted to help us.
"He was getting his hands pretty dirty."
A tornado swept through south Wichita on Saturday, causing significant damage but apparently no major injuries.
Williams happened to be in Wichita over the weekend helping a long-time friend, Duke Naipohn, build a cabin in the Wichita area, Naipohn told NFL Network insider Jason La Canfora on Tuesday. When the tornado struck, Williams suggested they go through the area with the Bobcat (a compact tractor), chainsaws and other building materials they had to help dig people out.
Naipohn said the house was spared in the storm.
They had helped a half dozen or so people by the time they got to Lyon, who was the only person that day to recognize Williams, Naipohn told La Canfora.
It was in no way a publicity stunt or anything of that nature, according to Naipohn. Williams' flight home was canceled due to the storms, so he and two friends tried to help others.
