Warriors fans intending to make the Guinness Premiership double-header a big part of their festive celebrations will have to be fast on their feet.
With more than a fortnight to go before the Sixways clash with Harlequins, fewer than 600 tickets remain.
Seats for the match - on Wednesday, December 27 (8pm) - are available in the North and East stands, but selling out rapidly for the South Stand.
And the news isn't much different for the London Irish match five days earlier, on Friday, December 22 (8pm). The Sixways ticket office reports that only around a thousand are left.
