Jared Payne, Rory Best and Andrew Trimble all return for Ulster as Les Kiss targets a playoff spot when they host league leaders Connacht tomorrow night.
The trio are among five changes to the starting team that faced Glasgow at Scotstoun last weekend.
Captain Rory Best comes in for Rob Herring to the front row following Ireland's Six Nations campaign, while Callum Black retains his position at loosehead, as does Ricky Lutton at tighthead.
Iain Henderson will make his first home appearance since December in the back row, and is joined by Chris Henry and Roger Wilson, who steps in for the injured Nick Williams.
Jared Payne and Andrew Trimble are back to full fitness and replace Stuart Olding and Rory Scholes, while Stuart McCloskey and Luke Marshall continue in the midfield.
Pete Browne replaces the injured Alan O'Connor in the second row, partnering Franco van der Merwe.
