Benetton now have an unassailable lead and will play the top South African side after this weekend’s games. The Cell C Sharks and Vodacom Bulls meet on Saturday, with the men from Pretoria basically needing only one point to make it through to the final.
Still, for the other sides, there will still be pride to play for in the final game of the season, as well as some opportunities for young players to make an impression.
Munster, who were one of the sides who had a chance until the cancellation, travel to Zebre to finish their season on a high.
Zebre have lost their last eight matches since beating the Dragons at home in February while their most recent success against an Irish province came at Connacht more than three years ago.
Munster have suffered just one defeat during the Rainbow Cup - against Connacht in the third round - and will be expected to see off Zebre this weekend, having won each of the past 16 meetings between these sides.
Johann van Graan's men, who have lost once away from home since January, were 52-3 victors at Thomond Park in November while they won the last encounter on Italian soil 28-0.
Leinster will be looking to bounce back from their defeat to Glasgow Warriors last weekend, but there is likely to be a lot of experimentation for them against Dragons on Friday night. Leinster have won the last nine meetings between the two sides and even though their form has been patchy, they should have enough to win the match.
Edinburgh’s search for redemption after a long season takes them to Llanelli this weekend where they will meet Scarlets.
The sides last met in what can only be termed a classic in February, where Scarlets won 27-25 in a thrilling encounter. Scarlets have, however, lost two of their last three games at home, but Edinburgh have won once in their last seven games.
Still both sides will want to finish off their season on a high.
