Newcastle United head coach John Carver suggested he may look to appeal Fabricio Coloccini's red card.
The Argentine defender was sent off during his side's 3-0 loss at Everton for a lunging tackle on Aaron Lennon in the 59th minute at Goodison Park.
Carver does not believe the challenge definitely warranted the sending off from referee Martin Atkinson but would view the footage a number of times before deciding whether or not to contest the decision.
"I have looked at it from four or five angles and it is not conclusive," he said.
"When it actually happened, from the reaction of the Everton players, straight away I thought 'that must be a red'. But when I came in and looked at it, it was very difficult to decide.
"I will look at it again and if it is worthy of a sending off then I will accept it but if it is not I will appeal.
"There seemed to be more of their players surrounding the situation than our players."
