The SA men are drawn in a strong pool which consists of Malaysia, Tonga and Scotland for the tournament to be staged at the Coventry Stadium.
The matches against Malaysia and Tonga are on Friday, while the clash against Scotland is scheduled for Saturday morning, with the quarter-finals later the same day.
“We start off with Malaysia and the important thing for us would be to get straight into our flow in that first game,” said Powell.
“Then we know Tonga will always be physical, and if we give them too much ball possession, they will make you pay for it.
“Scotland are a really good team. They managed to beat us the last time we met so we have to perform and hopefully do better against them. If we can manage to get out of our group then we cross pools (for the quarter-finals) with a group consisting of Fiji, Canada and Wales.”
All group matches and the men’s quarter-finals – between the top two teams from each pool – are scheduled for Friday and Saturday, with semi-finals and medal matches to be played on Sunday.
SA men's will face Malaysia (12.56 pm), and then Tonga (9.48pm) on Friday.
