Leinster will look to maintain pole position as United Rugby Championship leaders during the latest round of action this week.
The Irish side face their hosts Benetton, knowing victory at Stadio Monigo would keep them in top spot.
Ulster can climb back to the summit if they beat Kingspan Stadium visitors Cardiff on Friday night but it would be short-lived if Leinster triumph less than 24 hours later while Edinburgh are also in action on Friday as they take on Connacht at the DAM Health Stadium.
Third-placed Glasgow Warriors, tucked in a point behind Ulster, head to West Wales on Saturday for an appointment with the Scarlets, knowing a win on the road would keep them firmly in the mix.
The same goes for Munster, in fourth, who will attempt to make home advantage count when they tackle the Dragons at Thomond Park.
Welsh Shield leaders Ospreys, meanwhile, can consolidate that position at home to Zebre Parma on Sunday, with the Italian side yet to taste victory in the URC this season.
