You could be sitting on a £100 prize and not even know it.

Speedway fans are being urged to check their raffle tickets after one punter who scooped the lucky win is yet to come forward. 

While one player has claimed their £40 winnings already, there is still one mystery person yet to claim their takings.

Oxford Speedway tweeted: "If you hold either of these tickets please bring them to any of our next two home meetings to claim your prize!"

An hour ago, Oxford Speedway Supporters Club wrote on Twitter that Green 127 was claimed last night, but yellow 676 is still unclaimed.

They posted: "Even though the elements beat the Cheetahs tonight, we still drew the raceday jackpot. Yellow ticket 676 wins £100, green 127 wins £40. Keep your winning tickets and claim your prize in either of the next two home meetings!"
