OLEG Markov has been ruled out of Collingwood's clash against North Melbourne on Sunday.

While he was named in the Pies' side, the club withdrew the premiership defender from its squad on Saturday.

Reef McInnes has come into Collingwood's 23-man squad, with Ash Johnson now named among the emergencies.
