Fergie Keane on captain playing defensive role against Porto

MANCHESTER UNITED captain Roy Keane is likely to play in a defensive capacity against Porto tomorrow night following the withdrawal of Mikael Silvestre.

The French defender limped off with ankle ligament damage during Saturday’s 1-1 draw with Leeds after a 50-50 collision with Alan Smith.

“Mikael will be out for three weeks,” manager Alex Ferguson said. “It is a big blow for us but we will just have to get on with it.”
