McNabney ruled out of South Africa match after head injury on Ireland debut

James McNabney has been ruled out of Ireland's match against South Africa after a head injury cut short his international debut against Fiji, BBC Sport reported. The 23-year-old Ulster back row came off the bench during Ireland's 43-15 Nations Championship victory in Dublin, but his first appearance ended after only a brief spell on the field.

Watch the highlights:

Ireland coach Andy Farrell said McNabney had made an immediate impression with two powerful carries before being forced off. Speaking after the match, Farrell described the debutant as joking with team-mates in the changing room and said he remembered both breaks. Those comments accompanied the BBC's report that the injury would prevent him from featuring against the Springboks.

McNabney was not the only Ireland player whose afternoon was interrupted by injury. Centre Jamie Osborne also went off early, according to BBC Sport's match report. Ireland had made seven changes from the team that beat Argentina the previous week, with McNabney among the replacements selected for the Fiji fixture at Aviva Stadium.

The hosts eventually scored seven tries, but the final margin concealed a much closer first half. Tommy O'Brien crossed early and Robert Baloucoune scored twice before the interval. Fiji answered through Josua Tuisova and Peceli Yato, while Ben Volavola's kicking helped bring the visitors to within two points. Ireland led 17-15 at half-time after captain Tadhg Beirne had been shown a yellow card.

Ireland then added 26 points without reply after the break to secure the bonus-point victory. O'Brien and Baloucoune finished with two tries apiece, with Ronan Kelleher, Andrew Porter and Nick Timoney also on the scoresheet. The result kept Ireland one point behind France in the northern hemisphere standings, while England remained above them on points difference.

Farrell acknowledged afterwards that the scoreline was generous to Ireland, telling BBC Sport that Fiji had challenged his side in collisions, aerial contests and at the breakdown. He nevertheless stressed the value of winning under pressure. Ireland's next match is against South Africa in Dublin, with McNabney unavailable following a debut that showed promise before its abrupt end.
