Pakistan's Rumman Raees has been approved as a replacement for the injured Wahab Riaz at the ongoing Champions Trophy one-day tournament in Britain. Wahab suffered a tournament-ending ankle injury during Pakistan's crushing 124-run defeat by title-holders India in their opening match at Edgbaston on Sunday. Rumman, also a left-arm fast bowler, has represented Pakistan in two Twenty20 Internationals to date. The 25-year-old has also taken 123 wickets in 42 first-class matches. But Pakistan captain Sarfraz Ahmed indicated Junaid Khan, already with the squad, would replace Wahab for his side's second Group B fixture against South Africa at Edgbaston on Wednesday. Pakistan need to beat top-ranked South Africa if they are to have any chance of reaching the semi-finals of a tournament featuring the world's leading eight one-day nations. The Pakistanis conclude their group campaign against Sri Lanka in Cardiff on June 12.
