The Canterbury-Bankstown Bulldogs can confirm Marcelo Montoya has suffered a season-ending knee injury.

Scans on Monday morning confirmed the 23-year old had suffered a posterior cruciate tear, lateral ligament tear and medial meniscal tear to his left knee.

The results of the scans will see Montoya require an arthroscope to repair the lateral ligament and medial meniscus and at that time the surgeon will also assess the PCL and make a call on whether it requires reconstructing.

He will miss the remainder of the season and be sidelined for up to three months.

The incident occurred in the 25th minute of the Bulldogs loss to the Brisbane Broncos when he collided with fullback Anthony Milford.
