Tickets will be on General Sale from Wednesday morning from the Warriors Box Office on online.
Charlie Little, General Manager at Warriors, said: "Clearly there is only a one-week turn around between our game with Pirates and the quarter-final with Moseley and so we have set prices at a level where we hope as many fans will want to come and watch.
"We want to try and get Sixways buzzing and get as many people in to create a special atmosphere to generate a good cup run. Therefore we have decided to charge £10 for adults and children just £1 - kids for a quid - to try and support the community work that we are doing. We want to try and entertain the children at very little cost.
"Our Season Ticket holders made a commitment at the start of the year and we always strive to recognise that. They get additional benefits through the year and therefore it is important to be able to reward them with an exclusive buying period on Monday and Tuesday."
The club has also confirmed the Park and Ride will not operate this Saturday due to the quick turnaround of cup games.
"Because we have only got a week and because we wouldn't know if we are into the quarter-finals until late on the Saturday, we could not commit and pay for a Park and Ride service so that will not be in operation.
"However, we do have over 1,000 parking spaces on site and there are Park and Walk facilities near to the stadium that we would always encourage fans to use."
