The AFL will review LED fencing at all venues before the start of next round following the injury to North Melbourne captain Jack Ziebell at GMHBA Stadium on Saturday.

For the second time this season a game was marred by damage caused by signage on the boundary at a venue. Ziebell was forced from the ground for eight minutes during the third quarter of his side’s loss to Geelong after both his knees were cut when he made contact with the signage after chasing a ball to the boundary line in a contest with Cat Jake Kolodjashnij.

It followed the round three game at Perth’s Optus Stadium during which Geelong pair Mark Blicavs and Zach Tuohy both suffered cuts after making contact with similar LED lights on the boundary at the new venue.

Blicavs needed 14 stitches in his hand and led stadium management to cover the signage with plastic coating to protect players.
