Mark McCall has made five changes to his Ulster side ahead of Friday night’s Heineken Cup match against Biarritz at Ravenhill.
The Ulster boss welcomes Matt McCullough and Paul Steinmetz back from injury and shifts Andrew Trimble to wing to accommodate the latter.
James Topping and Rowan Frost who both featured last week are dropped to the bench.
