There should be skin and hair flying when losing Cup quarter-finalists Edinburgh and Ulster collide in Murrayfield tonight (KO 7.35, Premier Sports).
There is a lot on the line for both clubs and Iain Henderson (above) will captain the strongest side Dan McFarland can come up with against Richard Cockerill's charges.
Connacht can capture the two birds of a place in the Champions Cup next season and a place in the PRO14 League play-off this season with one more precious win at The Sportsground tomorrow (KO3.0, TG4).
They will have to do so against Cardiff Blues, the team who can replace them in third in Conference A.
