The Irish Rugby Football Union, in conjunction with Munster, Connacht, Leinster and Ulster Rugby, today launched a new concussion guide to educate those playing, supporting or officiating rugby.
In the semi final the 24 year old scorched in for two superb tries and was replaced immediately after he added the conversion of the second, to be kept fresh for the final.
It proved a clever ploy as Manning played a central role in what was a close final and a tense finish.
Manning also scored a try in the earlier round game against Leicester Tigers.
In the main event London Irish were beaten 15-12 by the Samurai side.
