RUGBY: Rory Best returns for Ulster's European Champions Cup game in La Rochelle

Best suffered a hamstring injury in mid September but was given the green light on Friday to take a spot on the bench for Sunday's European Champions Cup Pool A game at La Rochelle.

Andrew Trimble returns to the side having missed the last two games and he will become Ulster's most capped player of all time when he makes his 222nd appearance.

Robbie Diack will become the third player to reach the 200 cap milestone when he starts in France.
