Double trouble.

Clermont Auvergne attack the Ulster line. Ulster need every defender they can to keep the invaders out. Clermont break away right but the referee blows his whistle for a report by his assistant.

The assistant reports the illegal activities of the Clermont lock Nathan Hanes. At the back of a tackle/ruck as Clermont attack, his right hand has hold of Pedrie Wannenburg and his left has hold of Stephen Ferris. Both Ulster men demonstrate their desire to be free to defend.

the referee then penalises Clermont, bringing an end to a promising attack.

Hines is 35 years of age and has been capped 77 times for Scotland. One could have expected greater maturity from him.

Worth a yellow card?

Quite possibly.
