Western Bulldogs superstar Marcus Bontempelli will be assessed in the coming days after finishing Saturday night’s Semi Final on the interchange bench with a knee injury.

Bontempelli was an excellent contributor in the Bulldogs’ epic one-point win over the Brisbane Lions, but left the field after pushing forward late in the game and coming off second best in a crucial marking contest against three opposition defenders.

“He copped a knock to the back of his knee.  It’s difficult to know the extent of any injury,” senior coach Luke Beveridge told media after the game.

“He’s obviously a little bit sore.  We’ll need a little bit of time before we can assess it.

“He’ll probably get a scan when we get to Perth and see if there’s any damage in there.”

Bontempelli finished the game with 29 possessions, seven tackles and nine score involvements in a typically influential performance.

“I just landed quite awkwardly.  I was a bit ginger initially, so rather than limp around out there probably the right thing was just the interchange,” he told Channel 7 after the match.
