Before the game, however, they will be holding an opening training session at Kingsholm at 6:30pm on Tuesday. Entry is free of charge and open to everyone.
After the training session (which should last around an hour), the players will be coming in to the Shogun Bar and will be more than willing to sign autographs and pose for pictures.
Tickets are still available for Wednesday evening's fixture. With tickets priced from £8 for the Shed and £13 for a seat, it's a fantastic opportunity to see the Samoans in action before they take on England at Twickenham on Saturday.
There will also be a match programme on sale on Wednesday, priced at £2.50, with 50p from each programme sale going straight to the Royal British Legion.
