Ex-Rugby Football Union boss Martyn Thomas has voiced his dismay at the decision to only shortlist three rugby stadiums as venues for RWC 2015.
Thomas believes that tournament organisers had a "moral obligation" to utilise more homes of the Aviva Premiership sides at the upcoming event.
Instead only Kingsholm, the Millennium Stadium and Twickenham have been included on the list of venues, with Welford Road a surprise exclusion.
"It's a great shame, I'm very disappointed," Thomas told BBC Sport.
"There was a moral obligation to use more rugby stadiums."
Thomas, who was chairman when the RFU won the hosting rights, has since stepped down and disagrees with Leicester City's Soccer Stadium being preferred over Welford Road.
"Welford Road is a great venue and I think we've lost the chance to develop rugby clubs," he added.
"We wanted rugby stadiums. The great thing about Welford Road is that the Leicester faithful would have turned out even to watch a game between minnows.
"For a game such as Japan against Fiji for example, there's not a lot of point putting it in a stadium with a capacity over 20,000."
Critics of the plans think more rugby grounds should be utilised but organisers need to sell 2.9 million tickets in order to raise the £80m they have guaranteed to the IRB, with RFU chief executive Ian Ritchie saying Welford Road had not met the necessary criteria to host games.
"They do a great job, they are a fantastic club," he said.
"I can understand their disappointment but I think you've got to look at what were the facts of the review and the audit that went on."
