Edwina found three of the balloons released by Tigers at the Guinness Premiership game against Gloucester at the start of March in Wenhaston near Southwold, Suffolk.
Each balloon had a voucher entitling Edwina to a ticket to the Heineken Cup game against Bath at the Walkers Stadium on Saturday, April 11 (kick-off 6pm).
Now Edwina faces a big decision as she works for Ipswich Town, who play Doncaster Rovers on the same day.
She said: “We were there for the weekend in Wenhaston and went for a walk to explore the area. We were on a public footpath when we came across them in a hedge tied together.
“We couldn’t believe they were from Leicester. They had travelled quite a way. I was surprised to find that they travelled this far.
“It’s quite exciting. It’s something you don’t expect, do you?”
Edwina is the second person from Suffolk to strike it lucky with Heineken Cup tickets.
Farm worker Phillip Knights discovered one as he worked in a field in Blaxhall, near Woodbridge.
“I was working in the middle of a field,” said Phillip. “I was going along and there it lay. It had ribbons and, as luck would have it, the ticket was up the right way and said ‘winner’ on it.”
Tickets for the Heineken Cup quarter-final are now on general sale. They are available from the Welford Road ticket office or by calling 08701 28 34 30.
