McDonald, 22, is reported by Sky Sports to be undergoing a medical ahead of joining the Canaries from Dartford. He has been on trial at Carrow Road and had also interested Peterbrough, who brought George Boyd from non-league, Fulham, who recently sold former Gravesend man Jimmy Bullard for £5million, and Sheffield United.
McDonald, who is the second striker Bryan Gunn has signed today, joins Chris Killen in the newly-strengthened attack, the Celtic man having joined on loan for the season. McDonald is the latest in a long line of players to have been given the chance to step up from part-time football, with successes in recent years including Freddy Eastwood, Michael Kightly and DJ Campbell.
