CARLTON forward Harry McKay has withdrawn from Saturday's clash with North Melbourne at the Gabba. 

The Blues say McKay hyperextended his knee during a solo training session on Thursday, while he was barred from training with the main group due to a complication with his COVID-19 test. McKay's test later came through as negative. 

The key forward's absence makes room for former Richmond forward Callum Moore to make his Blues debut. Moore played eight games in four years at the Tigers before joining the Blues via the pre-season supplementary selection period.

Carlton coach David Teague said on Friday that McKay was set to play against the Roos, with one caveat. 

"As long as he's pulled up well from that session (he will be fine to play)," Teague said. 

"He did it by himself, which was a bit hard and we don't know exactly what he did, because he wasn't with the whole group."
