Robert Baloucoune is one of seven new faces in the Ulster starting lineup as they prepare to take on the Ospreys on Saturday (3pm kick-off, live on Premier Sports).
The Ireland wing makes his first appearance for his province since linking up with Andy Farrell’s Autmn Nations Series squad as he comes in to replace Craig Gilroy on the wing.
Elsewhere, after impressing in the win against Leinster, James Hume is given the week off with Angus Curtis slotting into the 13 jersey. Stuart McCloskey retains his spot in midfield.
Up front in the pack, Eric O’Sullivan replaces Andrew Warwick at loosehead who drops out of the 23 entirely as Jack McGrath starts on the bench. It is the first appearance for the 2017 Lion in 13 months due to a hip injury. Brad Roberts and Tom O’Toole also come in as part of a fresh frontrow from last week.
Kieran Treadwell replaces Sam Carter at lock, while Greg Jones drops out in favour of Sean Reidy in the backrow. Jones suffered a head injury last week at the RDS.
There is still no Duane Vermeulen as the Springbok number eight continues to recover from Covid.
Nathan Doak continues in a bench role as John Cooney keeps the starting scrumhalf jersey.
This is Ulster’s last URC action before a daunting trip to take on Clermont in their Champions Cup opener.
Ospreys for their part are captained by Wales international Rhys Webb who partners Stephen Myler at halfback. Alex Cuthbert starts in the backthree alongside Dan Evans and Luke Morgan, while international centre Owen Watkin lines out at 12.
Tomas Francis bolsters the frontrow while fellow international Bradley Davies starts at lock.
Gareth Anscombe can be called on from the bench, as can Irish-born former Highlanders lock Jack Regan.
