Lions look set to lose Sean O’Brien for final Test.

Leinster’s Sean O’Brien has been cited for dangerous play (swinging arm) during Saturday’s second Test victory over the All Blacks.

The Carlow back row is alleged to have used a swinging arm on All Blacks winger Waisake Naholo in the 59th minute of the game.

O’Brien faces a disciplinary hear this morning and with a suspension likely, it would mean he would miss next Saturday’s final Test. What a huge loss he would be

A statement from New Zealand Rugby reads:

British & Irish Lions loose forward Sean O’Brien has been cited for dangerous play during the second Test of the DHL NZ Lions Series, held at Westpac Stadium, Wellington.

Citing Commissioner Scott Nowland [Australia] has cited O’Brien under law 10.4 (a) for allegedly striking All Blacks winger Waisake Naholo with a swinging arm. The citing commissioner said the incident, in the 19th minute of the second half, is deemed to have met the threshold for a red card.

A judicial panel consisting of Adam Casselden (AUS), David Croft (AUS), and John Langford (AUS), will hear the case tonight at 8pm, at the New Zealand Rugby offices.
