Carroll, who moved from Tyneside to Liverpool for £35million in January 2011 and has since been loaned to West Ham, has enjoyed a return to form in recent weeks.
That comes in stark contrast to the Magpies, who remain embroiled in the scrap for Barclays Premier League survival after a 6-0 mauling by Carroll's parent club last weekend.
West Ham can inflict more pain on their former boss Alan Pardew if they win tomorrow afternoon and McDonald, an ex-Newcastle player himself, reckons Carroll will be up for the reunion.
"He is a forward and wants to score goals so I imagine he will be licking his lips after their performance against Liverpool last week," McDonald said.
"He is bound to find it strange because this is the club where he grew up and came through the ranks. That won't stop him trying to do his best for the team and he is fully committed to West Ham.
"He will be desperate to score and keep up his fine run of form."
