If free agent wide receiver Wes Welker doesn't find a team to sign with before the 2015 NFL season starts, maybe he should thinking about quitting football and getting into horse racing full-time, because apparently, he's got a knack for finding winning horses.

Welker's horse, Undrafted, was the surprise winner at the Diamond Jubilee Stakes at Royal Ascot in England on Saturday.

Thanks to the win, Undrafted earned the winner's share of $472,852 for his team, according to America's Best Racing.

Undrafted didn't just win big money for his team either, the horse also won big money for anyone who bet on him. Welker's horse went off at 14-to-1 odds when the race started and paid out $34.80 per $2 win bet.

The Diamond Jubilee Stakes is one of the prestigious races in Europe. It's so big that Queen Elizabeth actually presented Undrafted's trainer, Wesley Ward, with the trophy.

"I am just elated," Ward said, via ABR. "This is the biggest race I've won -- I've won Breeders' Cups and races here in the past, but to come here and be presented with a Group 1 trophy by the Queen was such a fantastic experience."

Welker wasn't in England for the race, but he did tweet about Undrafted's win.

Welker's had a serious run of good luck at the track over the past 13 months. In May 2014, the former Broncos wide receiver was overpaid $15,000 in winnings at Churchill Downs and ended up keeping the money.

A month later, in June 2014, Welker watched as Undrafted won $165,00 after winning the Jaipur Race at Belmont Park.
