Bulldogs forward Aaron Naughton has sustained a moderate grade medial ligament injury to his right knee, scans have confirmed.

There has been no damage to his ACL.

Naughton was removed from the game during the second quarter after his knee was caught in a tackle. 

The Club will work through a return to play plan in coming days but expects to be without the 24-year-old for at least the next four to six weeks.
