Ireland winger Simon Zebo has emerged as an injury concern after injuring his knee in an open training session today.

The Irish rugby team are preparing for the upcoming World Cup and during the session in Galway, Munster's Zebo had to leave the field of play and had an ice pack and bandage applied to his knee.

Gordon D'Arcy and Isaac Boss also suffered physical issues during the session.
