Arbroath 0 Celtic 1Adam Matthews' first goal for Celtic proved good enough to send Neil Lennon's team into the fifth round of the Scottish Cup but their replay win also owed much to a controversial disallowed goal by Steven Doris.

Matthews fired a wonderful strike from 20 yards in the 19th minute but Celtic subsequently failed to take control at Gayfield. And they were grateful for a 66th-minute decision by referee Craig Charleston, who presumably ruled out Doris’s close-range finish for an earlier infringement on Celtic goalkeeper Fraser Forster, but a foul did not appear obvious.

Forster himself averted extra-time when he saved a one-on-one with Connor Birse as Celtic edged through to set up a trip to Raith Rovers.

But it was from Paul Sheerin’s corner that led to the contentious decision. The Arbroath player-manager delivered right into the heart of the goalmouth and Forster could not collect. Hamilton won the high ball and headed down towards goal with Doris forcing the ball home on the line.

However, Charleston signalled for a free-kick.
