After fouling Alex Cochrane of Heart of Midlothian during Sunday’s Scottish Premiership game at Tynecastle Park in Edinburgh, Scotland, Yang Hyun-jun of Celtic, left, responds. [AP/YONHAP] Celtic has appealed the decision to substitute Yang Hyun-jun during the Scottish Premiership game against Heart of Midlothian on Sunday.After hitting Alex Cochrane with a high boot during Sunday’s league match at Tynecastle Park in Edinburgh, Scotland, Yang was originally given a yellow card.However, following a VAR review, referee Don Robertson overturned that decision and awarded Yang a straight red card in the sixteenth minute. Yang has not worn a red since joining Celtic the previous year. Celtic lost 2-0 while down a man. Celtic confirmed they will appeal the ruling in a statement posted on their official X account on Tuesday. The team said that they have “serious concerns regarding the use of VAR and the decision made within the match” in a letter to the Scottish Football Association.Brendan Rodgers, the manager of Celtic, also voiced his displeasure with the referee’s decision.After the game on Sunday, Aaron Rodgers remarked, “I know that they make mistakes and whatever else, but that felt like really poor officiating today.” “The first one, I believe, shows no force, but if you display a still photograph of it, it naturally appears to be a high boot with a head close to it. It is not how the move actually is. Yang received his red card because he had observed an increase in the team’s performance in recent games. Prior to Sunday’s match, he had two straight assists in league games.Yang, who played as a regular winger pick for Gangwon FC in K League 1, joined Celtic prior to the 2023–24 season. Despite this, Yang struggled early in the campaign. The 21-year-old scored the team’s first goal in November of last year, but he did not play well in the aftermath, which caused Rodgers to criticise him and reduce his playing time.Given his recent performance gains, he might get back more playing time.It is unclear if he will be able to participate in Celtic’s upcoming league game on March 16 against St. Johnstone. As of the time of publication, the appeal is scheduled for a hearing on Tuesday.As of Tuesday at press time, Rangers were leading the league by two points, with Celtic in second place with 68 points. Both teams have nine league games left, and the league schedule is scheduled to conclude in May. GET MORE RELATED CONTENT ON SPORTWORDS.CO.UK
