At least one change will need to be made by the Western Bulldogs at the selection table, with last week’s debutant Callum Porter ruled out of Wednesday night’s game against Richmond.

Porter copped a knock to his shoulder in a debut win against the Gold Coast Suns but came back on to play an important role in a tense finish.

A no risk approach will be taken with the young midfielder.

“In his first game in the AFL, Cal received a hit to his shoulder and it’s caused a minor grade AC injury,” medical services manager, Chris Bell, said.

“He’s going to miss the next one to two weeks.”

The Bulldogs will also be unable to call on forwards Bailey Dale, Josh Schache and Tory Dickson against the Tigers.

Dale was ruled out of last week’s game with a minor ankle injury, while Dickson (quad) and Schache (concussion) were both injured in a scratch match against the Suns. 

All three are expected to return to availability within the fortnight.
