Samuels threw the challenge following Poonia's pre-Games comment that the Australian's "poor form" was the actual reason the world champion did not compete at New Delhi.

While Samuels said that her concerns about health and safety were behind her decision to withdraw, Poonia told the media that the Australian hadn't performed well during the European summer.

Poonia's throw of 61.51 metres made her the first Indian track-and-field athlete to win a Commonwealth gold medal in over 50 years.

"It could be enormous," Sydney Morning Herald quoted Samuels's manager, Hayden Knowles, as saying.
