Sky Sports: Mohamed Diomande red card: Rangers midfielder’s red card at Dundee United splits Kris Boyd and Chris Sutton.

Rangers will appeal Mohamed Diomande’s red card late in the club’s 3-1 victory over Dundee United on Sunday, according to Philippe Clement. Kris Boyd finds Nick Walsh’s decision ’embarrassing,’ but Chris Boyd accuses Diomande of’slapping’ Kevin Holt. Kris Boyd found it “embarrassing” that referee Nick Walsh stood firm in his decision to dismiss Rangers midfielder Mohamed Diomande despite being requested to undertake an on-field review. Walsh showed Diomande a straight red card late in Rangers’ 3-1 victory against Dundee United after he collided with Kevin Holt, however it was unclear what the particular offence Walsh had noticed was. The referee was urged to undertake an on-field review but refused, confusing Philippe Clement, who stated that Rangers will appeal.”It’s embarrassing,” admitted former Rangers striker Boyd. “I believe that when you go to the monitor, you can become overly stubborn. Sometimes you just have to acknowledge you’re wrong, and Nick Walsh should have. “There is no excessive force, there’s no brutality and if I’m Rangers I would have my appeal in right now.” Replays revealed that Diomande’s right hand may have made contact with Holt’s face as they battled ball possession, but Boyd added: “It’s a little bit inconclusive, even if he slaps him.” “There is no excessive force involved. There is no cruelty at all.
