Bournemouth boss Eddie Howe felt Steve Cook's dismissal in defeat to Norwich City was the result of a natural reflex.
Ondrej Duda's goal-bound effort looked to be going into an empty net before Cook's fingertip save pushed the ball on to the post and saw him dismissed by referee Paul Tierney.
Teemu Pukki scored the game's only goal from the resulting penalty.
"He hasn't planned it," Howe said. "He has just stuck his arm out. He is very down and we need to support him.
"When you are in the moment we are in, these things tend to happen. You find a way to hurt yourself and that is exactly what we did."
"The frustrating thing is that we created chances [to get a result]," added Howe, who also saw Wilson squander a golden opportunity in the second half. "We are not scoring enough and that is damaging our belief that we can win games.
"It puts pressure on the defensive side, which I don't think we have been bad at."
