HANGZHOU, China — Kylem Progella and Grydelle Matibag closed their campaign in the pool play on a sour note after handing the victory to Taravadee Naraphornrapat and Kongphopsarutawadee of Thailand in the women's beach volleyball event of the 19th Asian Games at the Ningbo Banbianshan Beach Volley Center in Ningbo, China.

Progella withdrew after suffering a back injury in their previous match against Kin Teng Tam and Ken Lai Lei of Macau on Thursday.

"She hurt her back so we decided not to play anymore," team manager Mayi Prochina said.

"We asked her the level of pain from a scale of 1 to 10. She answered seven. So we decided to just warm-up for compliance and withdraw from the match."

With the loss, the Progella-Matibag tandem wrapped up its pool play campaign with a 2-2 win-loss card.

It, however, still advanced to the knockout stage and Prochina expects Progella to be in great shape.

"The important match is the quarterfinals. She needs to recover so her condition will improve," Prochina, a member of the team that won the silver medal in the women's indoor volleyball event of the Singapore Southeast Asian Games in 1993.

"We have yet to know our opponent in the quarterfinals. We still have a drawing of lots."
