Alloa manager Jack Ross believes Craig Gordon would have been sent off had his challenge on Greig Spence been made by an outfield player.

The Celtic goalkeeper was shown a yellow card for the high tackle on the Wasps striker, cleaning out Spence as he rushed off his line.

The Scottish Premiership side went on to win the League Cup clash, making the competition's semi-finals with a 2-0 home victory after goals from James Forrest and Moussa Dembele.

"I was asked the question first before I had seen it again," Ross said afterwards.

"My question to the fourth official at the time was, was it a goalscoring opportunity and he said he didn't think it was an obvious one so that was fine.

"Having now seen the pictures, the actual type of foul - I think if an outfield player makes that challenge it is a red card.

"If one of my midfielders makes that in the middle of the park, as high as that, it is a red card.

"Having seen it now it is a dangerous challenge and I think it should have been a red.

"However, what I would say to temper that is that we carried good fortune in that game at times.

"Our goalkeeper played well but equally we got breaks at important times in terms of some of the chances Celtic missed so I wouldn't complain about it."

Asked about the Gordon incident, Celtic manager Brendan Rodgers said: "I haven't seen it clearly again. The fourth official and linesman were blocking me. I will have a look at it."
