Repeated concussions from head knocks left New South Wales Waratah's Berrick Barnes to take an indefinite break from rugby this season.

"I'm not hiding from the fact that I've been a bit frustrated and anxious about things and that's probably causing some of the issues I'm having as well," said Barnes in an interview. "So to get away from the environment just for a little bit is probably going to be pretty beneficial in that respect."

Earlier this month, aside from requesting that he be allowed to wear a boxing-style head protection gear, the 25-year old player has expressed his sentiments about his career and long-term health: "I understand that footy is not a forever thing, I don't want to be affecting the forever part in any adverse sense."

Head injuries like concussions have also been a growing concern in rugby world that the International Rugby Board has issued last month new guidelines concerning its treatment.

In Australia however, the issue has claimed earlier attention. After being diagnosed with brain damage, retired Demons player, Daniel Bell, sought compensation from his club in March this year. He claims that his head injury, which now makes him struggle for words or names when tired or strained, is connected to a series of concussions he had during his career.

With the skills to play either flyhalf or inside centre, Barnes' break is deemed a loss to the Waratahs, especially with a match against the ACT Brumbies this weekend. Hopes are up however that Barnes will be back in the field before the World Cup begins this September in New Zealand.
