Digicel Fiji Sevens halfback Lepani Nabuliwaqa's future in the George Sevens is likely to come to an end after the pool games this morning.

The Naitasiri lad is carrying an injury which forced him out of the last pool game against Argentina.

Coach Waisale Serevi has kept everyone guessing with changes in his line-up in all of the 3 games and it is likely he will stick to the side that played Argentina to face Samoa in the quarterfinals.

Serevi is using Jerry Burotu, Rupeni Nasiga and Iliesa Ratuva in the forwards while Captain Emosi Vucago changing position and switching back to his favourite half back spot, Vereniki Goneva will come in at playmaker, Iveri Lavo at rover and Ratu Naisa Narukutabua on the wing.

In the George Sevens tonight, defending champions New Zealand will play USA at 9.59 in the opening quarterfinals.

Tournament surprise Portugal who beat Wales 19-17 and edged Kenya 14-12 before an outstanding performance to win against favourites Samoa 19-17, will take on Argentina in the second quarterfinal at 10.21 tonight.

New Zealand will take on USA in the first quarterfinal at 9.59pm.

Host South Africa will feature in the last quarterfinal in the repeat of last week’s final against England at 11.05pm.

Coach Paul Treu who is eyeing his first win on home soil said to win the tournament his players need to play against strong opponents.
