Celtic have appealed Yang Hyun-Jun's red card against Hearts.

The Parkhead club has launched its appeal with the Scottish FA following the decision to send the South Korean off in the 2-0 loss at Tynecastle yesterday.

The 21-year-old was initially booked by referee Don Robertson after he was punished for a high boot challenge involving defender Alex Cochrane.

VAR reviewed the incident though, with John Beaton advising his colleague to check the flashpoint at the pitchside monitor for a potential red card.

After consulting with VAR, and looking at the incident again, Robertson upgraded his decision from yellow to red, and Yang was sent off in the early stages of the game.

This decision upset Brendan Rodgers, as he hit out at the officials post-match for their incompetence costing the champions.

Now, the Hoops have issued their wider concerns about VAR, while confirming their appeal over Yang's impending suspension.

A club statement reads: "Celtic Football Club can confirm that it will be appealing the red card issued to Hyunjun Yang during Sunday’s match against Hearts at Tynecastle.

"We have also written to the SFA to raise our serious concerns regarding the use of VAR and the decisions made within the match. 

"As we have said before, for some time Celtic has sought to work with the footballing authorities with the aim of improving standards associated with refereeing and the use of VAR in Scotland, something which is clearly in the wider interests of everyone within the game."

Rodgers is facing punishment from the Scottish FA for his outburst at Beaton and Robertson after the game.

The Irishman, 51, uncharacteristically had a go at the referee and VAR in public while disecting his team's damaging lose in the capital. 

If cited by the compliance officer, who is understood to have been in contact with Celtic over the matter, he could face at least a two-game ban.
