Heart attack scare for James O'Connor: report

Toulon's Australian wing James O'Connor is under observation amid claims he suffered a heart attack on his team's bus.

The club confirmed overnight that the Wallabies star felt unwell after Toulon's last match, against Oyonnax.

"James O'Connor felt unwell in the bus taking the team back from the Oyonnax game," Toulon coach Bernard Laporte told RMC radio.

"The medical staff decided to take him to hospital and he underwent a considerable series of tests."

French media has reported that O'Connor suffered a heart attack.

"James O'Connor, the Australian international... suffered a heart attack last Sunday and was hospitalised for three days," claimed the rugby journal Midi Olympique.

Toulon, however, have hosed down that report.

"I can reassure everyone he's fine," said Laporte.

"He will play rugby again but he will undergo further tests next week.

O'Connor is expected to miss at least three weeks of competition.
