Worcester supporters are set to travel to the Madejski Stadium in huge numbers on Sunday after the club sold out of its away allocation of tickets.
Warriors were given 500 tickets in the East Stand of the stadium to sell for the Sunday showdown in Guinness Premiership (kick off 3pm).
And supporters have quickly snapped up the chance to witness the penultimate game of a thrilling campaign with all tickets sent to Sixways now gone.
Fans who still want to buy tickets are advised to call London Irish on 0870 999 1871 or visit the club’s website at www.london-irish.com
