Wales were forced into a late change minutes before kick-off of their Rugby Word Cup Pool C fixture against Portugal in Nice as Jac Morgan came into the side for Tommy Reffell, who appeared to be injured in the warm-ups.
No official reason was forthcoming for the change, but coach Warren Gatland has parachuted his co-captain straight into the matchday 23 and left his replacement loose-forward Taine Basham on the bench.
Wales are seeking back-to-back wins after a tense 32-26 victory over Fiji in their pool opener. This is the first match of the tournament for Portugal, who are returning to the World Cup after a 16-year absence.
