Warriors are urging fans to move quickly to guarantee a spot for the final day showdown with Saracens with only a few tickets now available.
Warriors brought forward ticket sales for the home clash after a huge surge in demand from supporters as the relegation fight in the Guinness Premiership heats up.
And the Sixways Ticket Office has been inundated with requests all week as fans have eagerly snapped up tickets for the match which is just over four weeks away.
The last few tickets are expected to sell quickly and supporters are advised to book now to avoid any disappointment.
Warriors also have a limited number of corporate dining packages for the top-flight clash. For more details call Helen on 01905 459323.
Worcester Warriors General Manager Charlie Little said: "We have been delighted by the number of tickets already sold for the final day and would urge fans to act quickly to buy the final few available.
"Our next three fixtures are all crucial, with our destiny back in our own hands, and the last day against Saracens and the support of a packed Sixways crowd will be an occasion truly not to be missed."
Fans can get their hands on the last few hundred tickets by visiting the Sixways Ticket Office or calling 0870 990 5650. The Ticket Office is open Monday to Friday between 9am and 4.30pm.
