Ben Hilfenhaus, the Australia and Tasmania fast bowler, has been signed up by Delhi Daredevils to replace JP Duminy, who withdrew from IPL 2017 owing to personal reasons.

Hilfenhaus, who retired from first-class cricket last year, played a key role in Melbourne Stars' run to the semi-finals in the Big Bash League 2016-17. With 12 scalps from nine games at an economy of just over eight, Hilfenhaus, 34, finished as his team's second-highest wicket-taker behind Scott Boland.

In December last year, Hilfenhaus also picked up career-best figures of 5 for 23 playing for Canterbury against Otago in the Super Smash. Daredevils open their campaign against Royal Challengers Bangalore at the Chinnaswamy Stadium on Saturday.

Royal Challengers have made a replacement of their own, roping in Kerala wicket-keeper batsman Vishnu Vinod after KL Rahul was ruled out of the tournament with a shoulder injury. Vinod, 23, was the fifth-leading run-getter in the inter-state T20 tournament, where he scored 199 runs in four matches at a strike rate of 164.46. He also smashed 14 sixes, the most by any player, in the tournament.

Rising Pune Supergiant, meanwhile, have picked up Tamil Nadu allrounder Washington Sundar to replace R Ashwin, who is recovering from sports hernia. Seventeen-year-old Washington, who was part of the India team that reached the final of the Under-19 World Cup in 2016, made promising first-class and List A debuts in the 2016-17 domestic season. Washington, who was in and out of the Ranji Trophy team this season, was part of the Tamil Nadu team that won the 50-over Vijay Hazare Trophy and the Deodhar Trophy. He has scored 85 runs in six List A innings and has taken seven wickets in the eight matches he has bowled in.

"I am very happy to be a part of this team," Sundar told ESPNcricinfo. "It's a great privilege to be sharing the dressing room with some of the legends of the game."
