WESTERN Bulldogs premiership forward Toby McLean has been dealt a cruel blow after rupturing his anterior cruciate ligament for the second time in as many years.

McLean, who underwent a knee reconstruction last year and recently returned to the field, suffered the injury in a training session at Whitten Oval on Saturday.

The 25-year-old underwent a reconstruction last year after the injury in round 17 but won a recall in round 14 this season and played three consecutive games before being omitted.

The 2016 premiership player, however, is set for another long stint on the sidelines that is expected to last until late in the 2022 season after suffering the injury to the same right knee. He is set for surgery this week.

McLean, who was drafted by the Bulldogs in 2014, has played 94 games for the club and booted 14 goals from 15 games in the Dogs’ historic breakthrough premiership campaign.
