The former England full-back was sent off in Saturday's 1-1 draw with Hull City and will now be suspended until he returns to parent club Manchester City next month.
"We have been discussing the situation with City in terms of keeping Danny," said Pardew.
"We need to absorb what happened here on the back of that.
"It's difficult to reflect now. He will miss three games, so we have a big decision to make."
"It (the red card) was for something he said and not something he did. I'm afraid that's inexcusable."
