Paul Marshall says Ulster must keep composure

Roger Wilson will make his 200th appearance for Ulster when the Guinness Pro12 table-toppers welcome Scarlets to Kingspan Stadium tomorrow afternoon.

Wilson, who lifted European Cup honours while making over 100 appearances for Northampton Saints during his four-year spell in the midlands, is one of a number of changes to the side that defeated Glasgow last week.

With Ruan Pienaar on the bench, the lively Paul Marshall starts as pivot with Paddy Jackson wearing the number 10 jersey and also leading the side in place of injured Rob Herring and the otherwise engaged Rory Best.
