Scottish FA head of referee operations Willie Collum says goalkeeper Jack Walton’s yellow card for a foul on St Mirren forward Toyosi Olusanya should have been upgraded to red in Dundee United’s 2-0 win last month.Walton raced out of his goal and wiped out Olusanya, catching the forward high just outside the penalty box.”This is not denying a goalscoring opportunity, but it is serious foul play,” Collum said on the Scottish FA’s VAR Review show, external. “The height [of the tackle] is important here. There is speed, there is intensity and it meets the criteria of endangering the safety of an opponent.”It should have been an on-field review to recommend a red card for serious foul play.”Sandi Toksvig is joined by Gyles Brandreth, Lulu, Emmanuel Sonubi and Alan DaviesGrab the mic for Queen, Taylor Swift, Bon Jovi, Katy Perry and more…Ben Fogle and Kate Humble are back for the festivities at Longleat Safari ParkFrom micro plastics in our air, soil, and waterways, to the extent of food waste at this time of year© 2024 BBC.
