Makes sense so , was it serious?

Leinster win the lineout and Gibson-Park clears downfield

Nacewa is gone off

Cheetahs are penalised for not releasing. Byrne finds touch beyond the 22

Put joey in 10 nacewa 15 and Rory on

Cheetahs up to Leinster 22

The ball is knocked on by Noel Reid resulting in a Cheetahs scrum

Leinster manage to turn the ball over

Byrne sends the restart deep downfield and now the Cheetahs look to come on the attack from deep

Anyone know why isa is gone?
