The last we saw Wes Welker, the NFL receiver was walking out of Churchill Downs on Kentucky Derby Day with stacks of money and handing out hundred-dollar bills to strangers.

Churchill Downs spokesman Darren Rogers said Friday that "an individual believed to be a member of Wes Welker's group" received overpayment of more than $14,000 on a winning wager because of a tote error.

The track sent a letter to that individual "in an attempt to resolve the matter." Yes, Churchill wants its money back, but Welker is under no obligation to hand it over.

A horse owner who's no stranger to the business, Welker went on NBC's Dan Patrick Show on Friday and said he's not returning the winnings.

"It became very clear that the mistake occurred on our end when the patron was cashing several winning tickets after the Derby," Rogers said.
