Brent Reilly in stable condition after skull fracture

ADELAIDE Crows doctor Andrew Potter said the fractured skull sustained by midfielder Brent Reilly was more likely to occur in high-speed activities such as downhill skiing or motor racing than at AFL training.

Potter told reporters it was "far too early" to know whether the 31-year-old would play again, explaining a steel plate had been inserted in Reilly's skull to stabilise several breaks in the left side of his skull.

"He's breathing by himself, his condition hasn't deteriorated overnight - it's remained stable and he's communicated with his wife and family this morning and last night," Potter (pictured) said.

The last player to fracture his skull in an AFL game was St Kilda's Justin Koschitzke against the Bulldogs in round six of the 2006 season.

Originally expected to miss up to six weeks, he did not play again that season, but returned the next year and eventually retired in 2013 after reaching 200 games.
