Following a thoroughly unconvincing cameo display against England, Ireland's veteran fly-half Ronan O'Gara should consider calling time on his international rugby career.
The 35-year-old, who made his debut against Scotland in 2000, has racked up an impressive 127 caps for his national side during a decorated 13-year spell, which saw the fly-half play a part in Ireland's Grand Slam success almost four years ago.
However, O'Gara's 127th appearance was one to forget after the Munster legend came on to replace Jonathan Sexton - who had strained his hamstring trying to boot the ball down field - just after half-hour mark in a 12-6 defeat by England at the Aviva Stadium on Sunday.
When Sexton pulled up with his injury, on paper at least, O'Gara seemed a more than capable replacement despite his ageing legs - he is the all-time record points scorer for Munster and Ireland, and the second-most capped international rugby player in history.
In torrid conditions such as those that the hosts and England were forced to contend with in Dublin, O'Gara's experience should have been a valuable commodity that could switch the momentum of the match in Ireland's favour.
However, O'Gara painfully struggled in one of the biggest matches which the veteran has featured in during the twilight of his career. Such was his lack of playing time at this level, there was an audible groan of despair when it became apparent he would be replacing Sexton.
Presumably, Kidney's decision to have O'Gara as back-up to the Leinster fly-half is to have a steady deputy capable of doing an adequate job should Sexton pick up an injury, but his understudy on Sunday looked noticeably off the pace.
O'Gara's kicking was poor. When Ireland received a penalty in the first half, he failed to put any distance on the kick as the home side were denied a chance to attack in England's 22 and instead trudged a couple of yards forward for a lineout.
Some might say that O'Gara was right to take little (or no) risks. But there's a noticeable difference between Sexton, who at his youthful exuberance best shows no fear, and an old-hand, who now has something to lose following a much-lauded career.
Of course, O'Gara's defenders will point to the six points which he landed to help Ireland erode away at England's lead. But when the Red Rose racked up six points despite James Haskell's sin-binning, the Munster man had a chance to peg the visitors' lead back to 12-9.
He missed a kickable penalty which he dragged wide of his near post to hand the initiative to England with 15 minutes remaining. To compound the setback, from the restart, O'Gara was penalised for not releasing the ball after he became isolated from his team-mates.
It resulted in a chance for Owen Farrell to stroke over his fifth penalty of the day, but the Saracens man, who showed the steely nerves of a seasoned pro, edged his effort narrowly wide.
Kidney will surely argue who else could he place on the bench? It's a problem rife across many areas of Ireland's squad - lack of depth - and the fly-half position isn't immune. The possible replacement include the highly-rated but inexperienced Ulster fly-half Paddy Jackson or Sexton's back-up at club level, Ian Madigan.
In stark contrast, Stuart Lancaster had Toby Flood as Farrell's replacement on Sunday, a player impressing for Leicester Tigers, while there's also Gloucester Warrors' out-half Freddie Burns. Should the Red Rose get desperate, there's always Jonny Wilkinson who Lancaster could recall.
O'Gara will always be remembered fondly by his adoring public for a series of telling contributions over the past decade or more, not least that drop goal which sealed Ireland's Six Nations Grand Slam triumph, but he's not longer a viable option to fill the fly-half role.
