Leicester Tigers will tackle European giants Toulouse by sending out one of the biggest packs ever assembled in the club's history.
The inclusion of Logovi'i Mulipola at loose-head prop and Steve Mafi in the back-row means Richard Cockerill has chosen a front eight of huge proportions.
For what is likely to be a monumental battle in the trenches, Leicester's bruising pack will weigh a combined total of 141 stones and average 17st 6lb per man.
Whether they have ever put together a heavier pack is unlikely and open to debate.
Hooker Tom Youngs is the lightest man in the forwards at 16st, while Samoan prop Mulipola is the heaviest at 19st 7lb.
They will be met with a similarly-sized unit from the home side, whose pack includes Mulipola's fellow Samoan prop Census Johnston, weighing in at 20 stones and huge 18-stone French international No.8 Louis Picamoles among some other seriously big units.
With a 35,000-capacity Municipal Stadium roaring approval and jeering their disapproval, there is little doubt that this first-round collision between two sides that have won the competition six times between them is going to be one of seismic proportions.
Tigers also include at full-back Scott Hamilton, who is returning from injury, and Marcos Ayerza is on the replacements' bench after returning from international duty with Argentina.
The titanic battle is one that Leicester Tigers director of rugby, Cockerill is looking forward to.
"It shows just how tough a competition this is when two teams like Leicester and Toulouse can meet in the first round of matches," he said.
"We have watched a lot of their games this week and there doesn't seem to be much structure in what they do.
"They have a good line-out and a good set-piece, but they just seem to go out there and play.
"There is no real pattern. If they are not happy, they kick the ball away and make you play from your own half.
"When you have the sort of quality that they have in their squad and the resources behind it, I guess you can just go out and rely on your natural ability.
"I watched them in Bordeaux last weekend in the Top 14. They were 27-10 down, then they look the lead, then they turned the ball over and Bordeaux scored. But they came back to win.
"We can't afford to turn the ball over against them and we have to make good decisions and play pragmatic rugby.
"Once they get into their flow, they play to the rhythm of the band so we have to be physical, play very well and keep them quiet. We have good enough players to do some damage."
Tigers' next European game is against Ospreys, at Welford Road, a week tomorrow at 3pm.
