RUGBY: Wasps captain Raphael Ibanez has announced his retirement from club rugby with immediate effect.

Following a period of rest and recuperation after a series of complex concussions, Ibanez has been forced to end his career on medical grounds.

Sustaining an initial concussion against Worcester Warriors in September 2008, Ibanez suffered further head injuries against Leinster in Dublin and Sale at Adams Park earlier this season and has since undergone a number of investigations while completing a recommended two month period of rest.

Subsequently Ibanez has attempted to gradually integrate back into training however he is still symptomatic when undertaking physical exertion.

Following a reassessment by a Wasps neurosurgeon and neurologist last week the decision has been made by the medical team, coaches and Ibanez to stop playing with immediate effect as the risk of serious injury are too great to warrant an attempt to play again.

"We all agreed that to avoid a bad injury it is time for me to stop playing," said Ibanez. "I tried everything to come back onto the pitch but it is just too risky."

Making the announcement today, on his 36th birthday, Ibanez who joined the club in 2005, has enjoyed great success as part of the Wasps outfit successfully collecting silverware in every competition since his arrival.

Appointed club captain at the beginning of the 2008/09 season, Ibanez will continue his involvement with the club working with the coaches and players this season as they drive their ambition for Guinness Premiership honours.
