Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
Isaac Boss who played for the full 80 minutes for Ireland against France on Sunday will start.
McCall also welcomes back Ulster favourite David Humphreys who has now fully recovered from his elbow injury. There is an injury concern with Roger Wilson so McCall has opted to name both Roger Wilson and new recruit Sam Harding as an either/or option, with a final decision will be made tomorrow afternoon.
Ulster are currently second place in the Magners League and will be hoping for a return to winning ways at Ravenhill.
Tickets for the promenade and terrace will be available to purchase at the gate tomorrow night.
