League: Youngster in for injured Luck

The New Zealand Warriors have added young front rower Leeson Ah Mau to their squad for Sunday's NRL clash against Manly at Brookvale Oval, after experienced loose forward Michael Luck failed a fitness test.

Luck (26) was originally named in the traveling line-up but has been undergoing assessment throughout the week after he was knocked out in a heavy tackle by Parramatta prop Fuifui Moimoi last Saturday night.

"Michael did a psychometric test yesterday and on the basis of his results he could have played against Manly this weekend," said team doctor John Mayhew.

"He hadn't been experiencing any difficulties since last Saturday night, but after discussing the situation with him, my recommendation was that he wasn't fit to play."

Luck, one of the NRL's most durable forwards, has played all but two of the club's 78 games since joining the Warriors in 2006.
