Jonah Lomu is humbled and excited to be part of a rugby team again following his lifesaving kidney transplant, he said at his presentation by the Cardiff Blues yesterday.

Lomu, attempting to revive his career after a kidney transplant in 2004, has a seven-month contract to play for Cardiff in the Welsh and European competitions and will be eligible for home games against Calvisano on December 17 in the Heineken Cup, and Newport on December 27 in the Celtic League.

Lomu said his first challenge would be to break into the 22.
