Ulster and Connacht welcome back their international heavyweights for Friday night's Pro 12 fixture at Ravenhill.
Les Kiss’s side are currently fifth in the table while Connacht currently have a four point cushion at the top thanks to last weekend’s win over second place Leinster.
In total Kiss has made five changes to his starting XV, with Ireland captain Rory Best, Andrew Trimble and Jared Payne all returning to the fold.
Payne's opposite number in Belfast will be Ireland midfield partner Robbie Henshaw who returns to Pat Lam's starting line-up at 15.
Iain Henderson will make his first home appearance for Ulster since returning form the injury he sustained last December, and he is joined in the backrow by Chris Henry and Roger Wilson, who replaces the injured Nick Williams.
Stuart McCloskey partners Luke Marshall in midfield, and they will be up against a Connacht duo of Peter Robb and Bundee Aki, who are retained after the Leinster victory.
For Connacht Rodney Ah You, who is bound for Ulster in the summer, replaces the injured Nathan White in the frontrow while Ultan Dillane returns to the bench after making his international breakthrough during the Six Nations.
Connacht boss Lam is without the injured AJ MacGinty. Sale Sharks announced on Thursday the back would be joining the North West club next season.
