Tickets for the Kingsholm Shed have now completely sold out for Sunday's Heineken Cup match against Cardiff Blues (3pm).
Kingsholm is expected to be close to its 16,500 capacity for the clash between the top two teams in Pool Six clash this weekend.
Tickets for both the Shed and High Tech Stand have already sold out leaving tickets available in the C&G Grandstand and west terrace only.
Gloucester were narrowly beaten in Round 2 by the Welsh regional side and sit second in Pool 6, just four points behind. A bonus point victory would see them move to the top - providing the Blues don't snatch a bonus point for themselves.
And Gloucester coach Dean Ryan says he will make wait to a decision on Olly Morgan's selection for this weekend's match with Cardiff Blues
The fullback is recovering after undergoing surgery on Sunday to reset a dislocated finger he picked up against Newcastle on Sunday.
His finger was not fractured as first feared and he suffered no tendon damage around the knuckle, and Ryan believes he could play a part in the Pool 6 fixture.
He said:" At this stage it is too early to say when he might play again and we would not make a decision about this weekend's game against Cardiff for another couple of days to let the injury settle down.
"But we are obviously extremely relieved that the injury was nowhere near as serious as first indicated because Olly is a key member of our squad and has been in outstanding form.
"He can begin his rehab almost immediately and with the number of games we have approaching it is vital we have players of Olly's calibre around the squad."
Gloucester's medical team will also monitor Mike Tindall's dead leg and he will continue to receive treatment this week.
Nearly 40 players were involved in the first Wales Under 18 training session of the season. WRU National Performance Manager Gethin Watts is excited at the potential shown by the group and expects the Regional Under 18 Championship to hone their skills even further.
