The officials for this Sunday’s Grey Cup game have been announced and the replay official who made a critical mistake in the Hamilton Tiger-Cats East semi-final loss to the Edmonton Eskimos will, once again, be in the command centre.

Jeff Harbin, whose failure to uphold a roughing the passer challenge by the Hamilton Tiger-Cats was later acknowledged by the CFL to be a mistake, wills serve as the video official – the so-called eye-in-the-sky – for the championship game between the Ottawa Redblacks and the Calgary Stampeders.

The referee will be 19-year veteran Andre Proulx, who will be working his seventh Grey Cup.

Harbin’s call in the East semi-final on Oct. 13 was one of two errors made on the same play late in the fourth quarter with the game time tied at 21. Ticat quarterback Zach Collaros completed a pass before taking a hit from Edmonton defensive end Odell Willis. A holding penalty against offensive tackle Brandon Revenberg negated the 17-yard gain and Hamilton challenged the hit on Collaros, looking for roughing the passer, but were denied by Harbin, who was serving as the replay official.

But CFL vice president of football Glen Johnson later acknowledged that the calls “do not meet the standard” set by the league.

Harbin was also responsible for a mistake in an October game that cost the Ticats in their fight for the East Division title.

While Harbin was in the replay booth both Division Final games last weekend and will now work the Grey Cup, the official who made the holding call, umpire Adam Paradowski, has not worked since.
