Connacht will add extra terracing to the Sportsground for the Pro14 clash with Leinster after fans snapped up tickets for Saturday night's provincial derby.
Andy Friend's men powered past the Scarlets in Galway at the weekend, producing they type of free-flowing, expansive game they so defined during the Pat Lam era.
It left Connacht with two wins from their first four games and teed the Westerners up for a humdinger with Leo Cullen's reigning champions.
Additional temporary terracing will be installed at both the Bohermore and College Road ends of the ground, which will potentially boost the attendance to over 8,000.
Kick-off at the Sportsground on Saturday is at 5.15pm.
