Terry Butcher, the Inverness Caledonian Thistle manager, heavily criticised referee Steve O'Reilly for sending off Greg Tansey during his Scottish Premier League basement team's 2-0 defeat by Celtic.
Midfielder Tansey was dismissed for an aerial challenge on Georgios Samaras in the 36th minute when the game was goalless, and it proved a decisive moment as striker Anthony Stokes scored twice to consign the home side to defeat.
"If anything it is assault by fingernail," said Butcher. "The player [Samaras] has gone down as if he's been scratched by a jaguar. There's no way it's a red card. I'm not happy. The usual happens: Inverness get a man sent off. We had a man sent off against Rangers, against Celtic and against Motherwell."
Butcher, who will appeal the red card, added: "It happens because referees are rushed into decisions. If they just step back and look at it, then they'd realise it's not a red card. I feel like saying: 'SPL, go and sort out the referees and let's get a bit of consistency'."
The Celtic manager Neil Lennon had special praise for substitute Ki Sung-yueng after the midfielder played a part in both of Stokes' goals. "Ki manipulates the ball well and passes it well," said Lennon of the South Korean, who has only recently recovered from a virus which hospitalised him.
Lennon added: "We were worried that he hadn't played much football in two weeks, that's why we didn't take the chance by starting him. But he felt a lot better and made a great contribution when he came on. It was important to win against Inverness."
