Playing for Tamil Union in Sri Lanka's domestic league, Chanaka Welegedara finished with incredible figures of four wickets for two runs from four overs which included two maidens, equalling the world record for the most economical four-over spell.
The Champions Trophy takes place in England and Wales between June 6 and 23, with Sri Lanka due to face New Zealand in their opening match in Cardiff on June 9.
In his first Test innings back Hughes was bowled by Chanaka Welegedara in the 59th over with a delivery that speared through a gap between bat and pad and crashed into his off-stump. But in his time at bat the 24-year-old showed enough improvement in his technique to raise hopes that he may yet become a Test regular for Australia.
Thisara Perera, the allrounder who starred in Sri Lanka
Sri Lanka seamer Chanaka Welegedara was on Saturday ruled out of the second and final Test against England due to a groin injury and replaced by Shaminda Eranga.
Left-arm opening bowler Chanaka Welegedera produced a career-best performance to put Sri Lanka in command on the second day of the second Test match against South Africa at Kingsmead on Tuesday.
Chanaka Welegedara is on track for a fast recovery from the groin strain and is likely to be fit for the fifth and final ODI against India in New Delhi.
