Fiji born Penrith skipper Petero Civoniceva is bracing himself for one of the toughest weeks of his life as he will confront Kiwi enforcer and Paramatta Captain Nathan Cayless, twice in seven days.

The two front rowers will squad off in an NRL clash tonight before heading to the Sydney Cricket Ground next Friday for the Centenary Test between Australia and New Zealand.

With Cayless determined to help resurrect the Eels ailing season, Civoniceva knows he's about to face a fired up forward pack led by his long-time sparring partner.
