WESTERN Bulldogs ruckman/forward Ayce Cordy will be sidelined for four weeks after scans revealed a stress fracture in his fibula.

The 202cm big man had scans on Friday, with a Bulldogs spokeswoman confirming Cordy's lower-leg injury to AFL.com.au on Sunday.

Cordy has played three matches for the Dogs this season, booting three goals, including two against the Brisbane Lions in round one.

The 22-year-old has played 17 games for the Dogs after being drafted as a father-son selection in the 2008 NAB AFL Draft.

Injuries and a light frame held him back in the early years of his AFL career, although he has added 26kg since first joining the club in 2009.

Cordy has been mentored by three-time premiership player and specialist coach Cameron Mooney throughout the pre-season and the Bulldogs hope he can form a strong partnership with fellow tall forward Liam Jones.
