Australian all-rounder Shane Watson is confident of recovering from a groin strain before the ICC World Twenty20.

Watson was ruled out of the second season of IPL.

Watson picked up the injury during the seven-wicket loss to Pakistan in the one-off T20 match in Dubai on Thursday and then returned to Australia rather than going to South Africa for an IPL stint with the Rajasthan Royals.

"My groin is pretty good, it's only a very minor sort of strain. But the medical staff at Cricket Australia thought it was better for me to come home and get over it, with probably a week or two's rest instead of flying over to South Africa," Watson said.

"We've got a couple or three weeks or so before the first practice match, so it should be plenty of time to get it right," he added.

The 29-year-old Queensland cricketer is just raring to return to action with his improvised bowling action which he feels would help him Perform better.

"I'm still so excited about improvements that are going to be in my bowling with little technical changes that I've made. I can't wait to be able to get out there in the next couple of weeks," Watson told Australian Associated Press.before the Twenty20 World Cup commencing in England next month.
