Hong Kong captain Semi Iafeta has been ruled out of the return test match against Tunisia tomorrow. Team officials have preferred to give the No8 more time to recover from a hamstring injury and be fit for the Asian Five Nations later this month. 'The news from Tunis is that everyone is available for selection bar Semi and Wayne [Whitney] who will miss the game due to the red card he picked up last week,' said Ivan Torpey, Hong Kong Rugby Football Union's head of performance. Iafeta hurt a hamstring early in the first encounter at Hong Kong Football Club last Saturday and sat on the touchlines with his right thigh heavily iced as Hong Kong struggled to a 25-12 victory. The Causeway Bay Rams player left with the rest of the 29-strong squad for Tunis after the match, but it was discovered his injury was more serious than initially diagnosed. 'John [Walters, the head coach] told me they didn't want to risk playing Semi. I think it is a precautionary move so he will be able to recover in time for our first game in the Asian Five Nations,' said Torpey. Torpey was confident Iafeta's loss would be minimal and Hong Kong would manage without his menacing physical presence. 'Semi was an early loss last Saturday and still we did well without him. I believe we have the depth in players to deal with his absence,' Torpey said. The ever-reliable Nigel Clarke, who moved over from openside flanker to fill Iafeta's position last week, is likely to start as No8, with newcomer Renaud Chavanis and Justin Gregory set to play the flanking roles. Torpey confirmed the referee for tomorrow's encounter will be a Tunisian. 'He will be from their [Tunisia Rugby Union] panel of referees,' Torpey said.
