'Quadzilla' Trae Williams to make rugby sevens debut for Australia

Australian sprinter Trae Williams will earn his first men's rugby sevens cap in the opening round of the Sevens World Series in Dubai next weekend.

Williams who switched from athletics to sevens in May, has a 100m personal best of 10.10 seconds, ranking him fifth on the Australian all-time list.

The 22-year-old Williams, nicknamed "Quadzilla" because of his massive legs, has earned the call-up after impressing in pre-season.

"It's really exciting to bring Trae into the playing fold," head coach Tim Walsh said.

"He has really thrown himself into the last six months and the outcomes have been great for himself and what he offers our whole squad.

"Quick, powerful and really keen to learn, he has earned his place in this team and I look forward to seeing him in action in Dubai."

"I'm really excited about this new adventure with the Aussie 7s," Williams said in May after signing a contract with Rugby Australia through until 2021.

"I've always loved rugby and to be able to potentially chase an Olympic dream through rugby is something I never expected. I want to grab this opportunity with both hands."

Williams played schoolboy rugby and rugby league in Brisbane and attended academy training sessions with NRL club North Queensland in 2014.

Australia have been drawn in pool B at next weekend's season opener in Dubai alongside Scotland, USA and Ireland.

New Zealand are in pool C with Wales, Canada and Samoa.

The World Sevens Series will be available on Sky Sport.
