Fullback Roger Tuivasa-Sheck has possibly met the most generous youngster in the Warriors fan base - after an offer of $5 to buy the injured star a new knee.

Tuivasa-Sheck, who is out for the rest of the season, Tweeted about the encounter yesterday.

The Kiwis fullback and big off-season signing for the Warriors suffered a season-ending ACL injury against the Bulldogs in Wellington last month.

He had to undergo surgery and is facing more than six months on the sidelines.
